Description
TECHNICAL FIELD
[0001] The present invention relates to a drive-integrated disk
with a disk drive.
BACKGROUND ART
[0002] Up to now, drive-integrated disks have been proposed.
Nevertheless, the disks are used as peripherals, and hence control
of each system is performed by a processor in an external
system.
DISCLOSURE OF INVENTION
[0003] The present invention provides a drive-integrated disk
(hereinafter, this is called an intelligent disk (ID)) having an
electronic circuit controlling an external system as a
peripheral.
[0004] In order to solve this task, a drive-integrated disk of the
present invention is characterized in that the disk comprises a
disk block for storing information, a disk drive unit for accessing
to the disk block, an electronic circuit block which connects to
the disk drive unit via a bus, and a data input/output terminal
group for connecting the electronic circuit block to an external
apparatus.
[0005] Here, the drive-integrated disk is formed in a card shape,
and the data input/output terminal group is located in
corresponding to a standard terminal group of an IC card. In
addition, the drive-integrated disk is formed in a card shape, and
the data input/output terminal group is formed as a connector at
least at an end of the card. In addition, a bootstrap program,
system programs, and application programs are stored in the disk
block and electronic circuit block is distributed at desired
positions.
[0006] The present invention can provide a drive-integrated disk
having an electronic circuit controlling an external system as a
peripheral.
BRIEF DESCRIPTION OF DRAWINGS
[0007] FIG. 1 is a sketch of an example of a drive-integrated disk
that is this embodiment;
[0008] FIG. 2 is a sketch of another example of the
drive-integrated disk that is this embodiment; and
[0009] FIG. 3 is a drawing of an example of internal construction
of the drive-integrated disk that is this embodiment.
BEST MODE FOR CARRYING OUT THE INVENTION
[0010] For more detailed description of the present invention, an
embodiment of the present invention will be described with
reference to attached drawings.
[0011] FIG. 1 is a sketch drawing of an example of a
drive-integrated disk that is this embodiment. Here, since an ID 1
is formed in a card shape (hereinafter, this is called an ID card),
the ID 1 can be substituted for an IC card by providing the same
connector pins as those of an IC card.
[0012] The ID 1 comprises a disk block 3 that is a disk surface for
storing information, an intelligent circuit block 2 mounted, for
example, in the central portion thereof as shown in FIG. 1, and an
optical disk drive unit 4 including a pickup (not shown) reading
(or writing) information from the disk block (surface) 3 of the ID
1, and a pickup drive circuit (not shown) to have the pickup seek
on the disk surface. Here, although the circuit block 2 is located
in the central portion of the disk in FIG. 1, the location is not
particularly limited, for example, it can also be located on a
whole surface at a side of the disk or in a middle layer of a disk
manufactured in plural layers.
[0013] FIG. 2 shows the ID card having a connector at an end. The
connector can be provided at the other end in correspondence to the
objective of the ID card.
[0014] It becomes possible to keep process speed of an ID card
system fast by avoiding limitation of quantity of data transfer and
transfer speed between the ID card and external system through
realizing bus connection between the ID card and a system side in
this manner.
[0015] FIG. 3 shows a constructive example of a computer system
including the ID of this embodiment.
[0016] The intelligent circuit block 2 has ROM 22 for storing
programs, RAM 23 for temporary storage, and a CPU 21 for executing
programs stored in the ROM 22 and RAM 23. Numeral 24 shows a
photocell that is necessary if the ID side has an independent power
source.
[0017] On the other hand, a display unit 11, a keyboard 12, a mouse
13, a printer 14, a buffer memory 15, a DMAC 16 having a DMA table
16a, a communication processor 17, and the like are connected to
the system block 10. In addition, the system block 10 can be a
computer system having multiple functions or a specific device
having a single function such as display and printing.
[0018] Connection between the intelligent circuit block 2 and
system block 10 is a contact type or a non-contact type of
bus-connection.
[0019] In this system, a CPU is not included in the external system
block 10, and hence all the components operates under control of
the CPU 21 in the ID 1. In addition, since an OS and application
data are stored in the disk block, the system block 10 can be
operated with the OS stored in an ID by inserting the ID. Thus, a
bootstrap program, system programs, and application programs are
stored in the disk block and electronic circuit block of this ID
with being distributed at desired positions of the blocks. By
providing a plurality of OSs and application programs in the disk
block 3, performing selection display on the display unit 11, and
further selecting from the display with the mouse 13 and the like,
various types of OSs can be selectively started up so long as a
system block 10 of a standard specification is provided.
[0020] In addition, according to this system, version up can be
performed by replacing the ID even if processor development
advances, like in the past several years, while users can freely
build computer systems in either the old or new versions since
hardware and software are in one-piece.
[0021] Hereinbefore, the present invention is described with
preferred embodiments. Nevertheless, the present invention is not
limited to the above-described embodiments and various changes,
additions, and modifications can be made within the spirits and
scope as set out in the accompanying claims.
