Description
BACKGROUND
[0001] Embodiments of the invention relate to analytical devices
and systems, and more particularly, to a cartridge having internal
slots for storing biosample plates wherein the cartridge may be
stored in the cartridge storage slots of tape library systems and
handled by the robotic mechanisms of the tape library systems.
[0002] Samples of biological matters are often analyzed in
bio-assay processes to detect the presence of bacteria, viruses,
cancer cells, and other substances of interest. The biological
samples are typically placed on biosample plates to be analyzed by
a biological detection instrument. The detection instrument may
record the analysis results of a biosample on a data storage medium
such as a computer memory, disk drive, magnetic tape, or compact
disk, which may include an identification tag to correlate the
biosample with the analysis results.
[0003] High-performance computer data storage systems such as
optical disc and magnetic tape libraries possess the automation to
facilitate the scanning and analysis of biosamples, and to tabulate
the resulting analysis data. For example, these systems may analyze
the biosamples using magnetic tape read heads to detect magnetized
nanoparticles attached to the biosamples. The biosamples and
analysis data may be stored in different locations following the
analysis, which make it difficult to correlate the biosamples with
the corresponding data when needed. For a large number of
biosamples and biosample plates, the task of correlating the
biosamples to their data becomes even more complex. It is desirable
to exploit the use of automation functions available in computer
tape library systems to facilitate the correlation and management
of biosample plates and biosample analysis data.
SUMMARY
[0004] The disclosure relates to a biosample storage cartridge, as
well as methods and computer program products configured for the

in one or more biosample plates in a holder of a biosample storage
cartridge, the biosample storage cartridge having an enclosure

DETAILED DESCRIPTION
[0015] Embodiments of the disclosure relate to biosample cartridges
that include internal storage slots for holding biosample plates
that may be scanned, analyzed, and handled by a computer tape drive
and stored in the cartridge storage slots of an automated tape
library. The biosample plates may contain biological samples that
are written to by electromagnetic tape heads. They may then be
scanned and read from by anisotropic magneto-resistive (AMR), giant
magnetoresistive (GMR) or tunnel magnetoresistive (TMR) read
elements to detect the presence of target substances or
micro-organisms in the biological samples. The biosample plates may
have a width of 12.65 mm (1/2 inch), which is the width of commonly
used magnetic data tapes. The biosample plate storage cartridge may
have the same form factor as data tape cartridges used in automated
data storage libraries and thus may be conveniently accessed,
manipulated, and processed by robotic mechanisms in these
libraries. The biosample cartridge may be handled through the same
library internal-external mail slot as a tape cartridge. The same
tape automation mechanisms and processes used in modern tape
libraries may be used for long-term biological-archival storage of
the biosamples contained in the biosample cartridge.
[0016] The biosample storage cartridge may include a plate holder
to retain a plurality of biosample plates in the cartridge when the
cartridge is moved, for example by a robotic picker in a tape
library, as well as when the cartridge is in storage. The plate
holder may have a plurality of parallel storage slots for receiving
the biosample plates, which may be in the form of thin strips of
glass or a similar material. The biosample plate storage cartridge
is described in detail below with reference to FIGS. 1-3.
[0017] Referring to the drawings and in particular to FIG. 1, there
is illustrated an exemplary biosample plate storage cartridge 100
in which a plurality of slots may be provided to hold the biosample
plates. The biosample plate storage cartridge 100 comprises an
enclosure 101, which may include one or more parts. The cartridge
100 may have a movable side door 102 that can be slid open, for
example by a tape drive, to gain access to the interior space of
the cartridge 100. The tape dive may be adapted to perform
biosample analysis. In one embodiment, the biosample plate storage
cartridge 100 may comprise a top shell 101A and a bottom shell 101B
wherein the top shell 101A is removably affixed to the bottom shell
101B by screws or other fasteners. Alternatively, the biosample
plate storage cartridge 100 may have a front, top, or rear door
that is movable to provide access to the interior space of the
cartridge.
[0018] The biosample plate storage cartridge 100 may have the same
size and exterior configuration as a magnetic tape storage
cartridge based on LTO (Linear Tape Open) technology, the IBM
TS1130 magnetic tape data storage cartridge, or the Oracle T10000
tape cartridge. In an alternate embodiment, older IBM single-reel
tape cartridges could be used, such as the 3480, 3490, and 3590
tape cartridges. In a data storage cartridge, a data storage media
such as a magnetic tape, may be mounted on a tape reel and occupy
the space inside the biosample storage cartridge 100 rather than
the biosample plates. Such a tape data storage cartridge may
comprise a cartridge brake release button to allow the tape reel to
freely rotate once the cartridge is loaded into a data storage
drive.
[0019] The biosample plate storage cartridge 100 may further
include one or more cartridge memories 103 for storing
identification information about the biosample storage cartridge
100, data related to the biosample plates, and analysis data
associated with the biosamples stored in the biosample storage
cartridge 100. Each cartridge memory 103 may comprise a transponder
having a wireless interface, which is retained in the cartridge
100, for example, by being encapsulated by the cartridge when it is
assembled. The encapsulation process is understood by those of
skill in the art as applied to a single cartridge memory.
[0020] FIG. 2 illustrates a biosample plate storage cartridge 200
with its cover removed to show the storage slots for holding
biosample plates, in accordance with an embodiment of the
invention. The biosample storage cartridge 200 comprises a plate
holder 204 for holding a plurality of biosample plates 205. The
plate holder 204 may be an integral part of the biosample storage
cartridge 200 or a separate part that is attached to the data
storage cartridge 200 by fasteners or adhesive. The plate holder
204 may comprise a plurality of parallel slots 206 to hold the
biosample plates 205 in place and prevent the biosample plates 205
from separating from the plate holder 204 when the storage
cartridge 200 is being moved. Movable door 202 is shown at the
bottom corner of the cartridge 200.
[0021] In one embodiment, the width of the slots 206 is slightly
larger than the thickness of the biosample plates 205 to snugly
accommodate the biosample plates 205 and firmly retain the
biosample plates 205 in the slots 206 by friction. In one
embodiment, the biosample plates 205 may have a thickness of 1.0 mm
and the width of the slots 206 is slightly larger than the
thickness of the biosample plates. For example, for a thickness of
1.0 mm for the biosample plates, the width of the slots may be in
the range of 1.05-1.2 mm. In an alternate embodiment, the material
containing slots 206 is elastic, such as a polymer or elastomer,
and the width of slots 206 is slightly smaller, ranging from 0.90
mm to 1.0 mm.
[0022] The biosample plate storage cartridge 200 may include one or
more cartridge memory 203 for storing data related to the biosample
cartridge 200, for example, the identification of the biological
samples, biosample plates, analysis data on the biological samples,
and relevant dates such as creation dates and analysis dates. The
cartridge memory 203 may be in communication with a wireless
communication interface to send information to and receive
information from a remote transceiver, for example, in a tape
library system that handles the biosample plate storage cartridge
200.
[0023] Although FIGS. 1-2 illustrate a biosample plate storage
cartridge that has the same form factor as a single reel magnetic
tape cartridge, the biosample storage cartridge may have the same
form factor as a dual reel cartridge, such as the IBM 3570
cartridge. In a dual reel cartridge, the magnetic tape is fed
between the two reels of the cartridge. Such a biosample plate
storage cartridge may comprise a biosample plate holder 204 in the
space occupied by the two tape reels, as similarly described with
reference to FIGS. 1-2.
[0024] FIG. 3 illustrates a cross-sectional side view of a
biosample plate storage cartridge 300 with storage slots for
holding the biosample plates 305, in accordance with an embodiment
of the invention. The biosample plates 305 are retained by the
slots in the biosample storage cartridge 300 as described with
reference to FIGS. 1-2. Cartridge memory 303 is shown at a
generally 45 degree angle, so that the memory may be wirelessly
accessed by either the robotic picker in the automated library or
the tape drive modified to perform bio-analysis.
[0025] FIG. 4 illustrates a block diagram of the functional
components of a memory component 403 and a wireless communication
interface 407, which may be part of a biosample storage cartridge
100, such as cartridge memories 103, 203, and/or 303. The memory
component 403 may store information about the biosample cartridge,
biosample plates in the cartridge, and biosamples on the biosample
plates. The memory component 403 may comprise a nonvolatile memory
409, such as an electrically erasable programmable read-only memory
(EEPROM), a phase-change memory, flash memory, NOR memory, or a
NAND memory arranged to operate in a low power environment. Memory
component 403 also may comprise memory processor 408, such as logic
or a microprocessor chip, for example, an Intel Pentium.TM. chip
arranged to operate in a low power environment, such as a portable
computer.
[0026] The memory processor 408 may have computer readable program
code embodied therein, including suitable security and
encryption/decryption algorithms, and the logic for accessing and
operating the memory component 403. The memory component 403 may
comprise a nonvolatile storage 409, as is known to those of skill
in the art. The nonvolatile storage 409 may comprise a separate
chip attached to the logic or memory processor 408, or may comprise
a portion of the same chip. The computer readable program code may
be stored in a nonvolatile internal memory of the processor 408 or
in the nonvolatile memory 409, and loaded into the processor 408.
Alternatively, the memory component 403 may be operated by a
control system or processor of an analytical system that uses the
biosample storage cartridge 100.
[0027] In the illustrated embodiment, the wireless communication
interface 407 may be a radio frequency (RF) wireless interface. An
example of an RF wireless interface is described in U.S. Pat. No.
4,941,201. A high frequency inductive wireless interface may also
be employed, which is of sufficiently high frequency so that it
does not adversely affect magnetic storage media that may be
present in a tape library system that handles the biosample storage
cartridge. Examples of high frequency inductive wireless interfaces
are described in U.S. Pat. No. 4,650,981, U.S. Pat. No. 4,758,836,
and U.S. Pat. No. 3,859,624.
[0028] The wireless communication interface 407 includes an antenna
410 for receiving an RF signal from an RF interface of either a
tape drive modified to perform bio-analysis or a robotic picker
that moves the biosample plate storage cartridge 300 in a tape
library system. The antenna 410 may be positioned at an angle in
the range of 30-60 degrees for optimal reception of the RF signal,
e.g., at 45 degrees as shown for the cartridge memory 303 of FIG.
3. The antenna 410 may be a quarter wave antenna, a fractal
antenna, or the inductor of an inductor-capacitor oscillator. A
coupler 411 supplies the received signal to a power conversion
circuit 412 and to a data demodulator 413. The power conversion
circuit 412 converts the received signal to a power current,
supplying the current on line 415 to all devices on the biosample
storage cartridge 300, including the memory component 404, the data
demodulator 413, and a data modulator 414. The received signal from
antenna 410 may be encoded. The data demodulator 413 receives the
incoming coded signal from coupler 411 and demodulates the signal
to provide data signals to the memory component 404 and for writing
to memory 409. Data signals being read from memory 409 and memory
component 404 are provided to the data modulator 414 which encodes
the signals for transmission by coupler 411 and antenna 410 to an
RF interface, which may be in either the robotic picker of the tape
library system that handles the biosample plate storage cartridge
300 or in the tape drive modified to perform bio-analysis.
[0029] FIG. 5 illustrates an automated data storage tape library
500 that may be used with the biosample plate storage cartridge
shown in FIGS. 1-4, in accordance with an embodiment of the
invention. The data storage tape library 500 is an automated tape
library that may include a number of tape drives 510 for reading
and writing data on magnetic tape media, such as single-reel or
two-reel magnetic tape cartridges. Examples of the library 500
include IBM TS3400.TM. and TS3500.TM. Tape Libraries. IBM
TotalStorage.TM. 3494 Tape Libraries, and IBM 3952.TM. Tape Frames
Model C20, which store magnetic tape cartridges and use IBM
TS1130.TM. tape drives. Other examples of the library 500 include
IBM TS3310.TM. and TS3100/3200.TM. tape libraries which store
magnetic tape cartridges and use IBM LTO (Linear Tape Open) tape
drives. Tape drives modified to perform bio-analysis accept
cartridge 100, 200, 300 from the robotic picker, withdraw a
biosample plate through door 202 of cartridge 200, and perform the
bio-analysis.
[0030] A plurality of cartridges 520 are stored in banks or groups
of cartridge storage slots 521. Cartridges 520 may comprise tape
media for data storage, tape substrate for biosamples, or biosample
plates 205 and 305 for bio-analysis. Tape media may encompass a
variety of media, such as that contained in magnetic tape
cartridges, magnetic tape cassettes, and optical tape cartridges,
in various formats. For universal reference to any of these types
of media, the terms "tape media" or "media" are used herein, and
any of these types of containers are referred to as "tape
cartridges" or "cartridges" herein. An access robot 523, including
a cartridge picker 522 and a bar code reader 524 mounted on the
cartridge picker 522, transports a selected cartridge 520 between a
cartridge storage slot 521 and a drive 510. Bar code reader 524 is
mounted directly on picker 522 so that the library 500 can check
the bar code on cartridge 520 before picking the cartridge and
transporting it to a drive 510, storage slot 521, or import/export
mail slot 526.
[0031] The automated tape library 500 further has a library
controller 525 which includes at least one microprocessor. The
library controller 525 may serve to provide an inventory of the
cartridges 520 and to control the library 500. Typically, the
library controller 525 has suitable memory and data storage
capability to control the operation of the library 500. The library
controller 525 controls the actions of the access robot 523,
cartridge picker 522, and bar code reader 524. Barcode reader 524
may read a barcode from cartridge 100, 200, or 300. The library
controller 525 is interconnected through an interface to one or
more host processors, which provides commands requesting access to
a particular biosample plate, a tape media, or a cartridge in
particular storage slots. A host, either directly or through the
library controller, controls the actions of the drives 510 which
either perform data 10 with tape media or, if suitably modified,
perform bio-analysis on the biosamples stored on plates 205 and
305. Commands for accessing data or locations on the tape media and
biosample plates, and information to be recorded on or to be read
from selected tape media and biosample plates, are transmitted
between the drives 510 and the host. The library controller 525 is
typically provided with a database for locating the cartridges 520
in the appropriate storage slots 521 and for maintaining the
cartridge inventory.
[0032] Library 500 also includes an import/export mail slot 526,
which is a portal allowing cartridges 520 to be entered into or
removed from library 500. Since cartridges 520 have a generally
identical exterior dimensions regardless of whether they hold data
tape or biosample plates, cartridges 520 may enter library 500
through import/export mail slot 526, picked up by picker 522 and
transported to either cartridge-storage slot 521 or drives 510.
Drives 510 would have a common cartridge loader mechanism, whether
the drive is a data drive or a bio-analysis drive, because of
cartridges 520 having identical exterior dimensions. Similarly
picker 522 may pick cartridge 520 from a drive 510 or
cartridge-storage slot 521 and place it in import/export mail slot
526 for removal from library 500. In an alternate embodiment,
biosample cartridges 520 are a different color from cartridges
containing digital data, as well as containing information
regarding their intended purpose in memories 103, 203, and 303.
[0033] FIG. 6 illustrates a block diagram of the functional
components in a tape drive that may be used for analyzing a
biosample and storing biosample identification and analysis data,
in accordance with an embodiment of the invention. The magnetic
tape drive 600 comprises a memory interface 631 for reading
information from and writing information to one or more of the
cartridge memory 632 of the magnetic tape cartridge 633, for
example, in a contactless manner.
[0034] A read/write system is provided for reading and writing
information to the data storage media, such as magnetic tape, or
nanoparticles on the biosample plates 205 and 305, and may comprise
a read/write head 634 with a servo system for moving the head
laterally of the magnetic tape 635 or a biosample plate (not shown
in FIG. 6). The servo system may comprise a read/write and servo
control 636 and a drive motor system 637 which moves the magnetic
tape 635 between the cartridge reel 638 and the take up reel 639
and across the read/write head 634. The read/write and servo
control 636 controls the operation of the drive motor system 637 to
move the magnetic tape 635 across the read/write head 634 at a
desired velocity. The read/write and servo control 636 may
determine the location of the read/write head 634 with respect to
the magnetic tape 635.
[0035] In one example, the read/write head 634 and read/write and
servo control 636 employ servo signals on the magnetic tape 635 to
determine the location of the read/write head 634, and in another
example, the read/write and servo control 636 employs at least one
of the reels, such as by means of a tachometer, to determine the
location of the read/write head 634 with respect to the magnetic
tape 635. The read/write head 634 and read/write and servo control
636 may comprise hardware elements and may comprise any suitable
form of logic, including a processor operated by software, or
microcode, or firmware, or may comprise hardware logic, or a
combination. In an alternate embodiment, tape 635 is simply a
flexible substrate, such as a MYLAR.TM. substrate, and biosamples
are stored directly on this substrate and wound around reel 638 in
cartridge 633.
[0036] A control system 640 communicates with the memory interface
631, and communicates with the read/write system, e.g., at
read/write and servo control 636. The control system 640 may
comprise any suitable form of logic, including a processor operated
by software, or microcode, or firmware, or may comprise hardware
logic, or a combination thereof. The control system 640 typically
communicates with one or more host systems 641, and operates the
data storage drive 600 in accordance with commands originating at a
host. Alternatively, the data storage drive 600 may form part of a
subsystem, such as a library, and may also receive and respond to
commands from the subsystem.
[0037] As illustrated, the data storage drive 600 provides
information to a cartridge memory 632 of the magnetic tape
cartridge 633, and provides data to the magnetic tape 635 of the
magnetic tape cartridge 633.
[0038] In one embodiment, the data storage tape drive 600 may
function as an analytical system for scanning the biosample plates
205, 305 and analyzing biological samples deposited on the
biosample plates 205, 305 to detect the presence of target antigens
or substances. The magneto-resistive (MR) heads of the read/write
head 634 in data storage drive 600 may act as the scanners for
reading data from the biosamples. Write heads of read/write head
634 may magnetize nanoparticles used to tag the biosamples which
are subsequently read or detected by the MR heads. For example, an
MR read/write head 634 may be used to detect micro-organisms and
antigens that are attached to magnetized nanoparticles.
[0039] An MR read-write head may scan a large number of biosamples
deposited on a magnetic tape media as the MR read-write head
traverses the tape media a high speed. The tape drive electronics
may then process the signals from the read-write MR head to detect
the presence of target micro-organisms or antigens in the
biosamples. Such as bio-assay process is described, for example, in
the commonly-assigned US patent application entitled "Detection Of
Analytes Via Nanoparticle-Labeled Substances With Electromagnetic
Read-Write Heads", Ser. No. 12/888,388, herein incorporated by
reference in its entirety.
[0040] FIG. 7 illustrates a block diagram of a representative
computer system, some of which may be incorporated in a data
storage tape library and a cartridge memory to provide control and
processing function, for providing aspects of the disclosure. Data
processing system 700 includes a processor 701, a memory 702, a
persistent storage 703, a communication interface 704, an
input/output unit 705, a display 706 and a system bus 707. Computer
programs are typically stored in persistent storage 703 until they
are needed for execution by an operating system running in memory
702. Persistent storage 703 may comprise one or more hard disk
drives and multiple hard disk drives may be organized into a RAID,
CD (Compact Disk) drives. DVD (Digital Versatile Disk) drives. BD
(Blu-Ray) drives, SSD (Solid State Drives), and solid state memory.
At that time, the programs are brought into the memory 702 so that
they can be directly accessed by the processor 701. The processor
701 selects a part of memory 702 to read and/or write by using an
address that the processor 701 gives to memory 702 along with a
request to read and/or write. Usually, the reading and
interpretation of an encoded instruction at an address causes the
processor 701 to fetch a subsequent instruction, either at a
subsequent address or some other address. The processor 701, memory
702, persistent storage 703, communication interface 704,
input/output unit 705, and display 706 interface with each other
through the system bus 707.
[0041] The subject matter described above is provided by way of
illustration only and should not be construed as limiting. Various
modifications and substitutions of the described components and
operations can be made by those skilled in the art without
departing from the spirit and scope of the present disclosure
defined in the following claims, the scope of which is to be
accorded the broadest interpretation so as to encompass such
modifications and equivalent structures.
