    [0001] 1. Field of the Invention [0001]
    [0002] The present invention relates to a disk drive system for accessing a disc-shaped storage medium such as an optical disk and, more particularly, to a disk drive system enabling access not only to a disk-shaped storage medium but also to a small-sized storage medium such as smart media. [0002]
    [0003] 2. Description of the Related Art [0003]
    [0004] In recent years, a wide variety of devices have been presented using so-called smart media (SSFDC: solid state floppy disk card) as recording media. [0004]
    [0005] The smart media are light-weight (2 g) and thin small-sized (length: 45 mm, width: 37 mm, height: 0.76 mm) flush memory cards which have a simple structure and are easy to carry to allow the use as a removable storage medium for a portable information terminal such as a digital camera. [0005]
    [0006] In addition, the smart media are suitable for helping making these applied products smaller and have excellent portability allowing themselves put between leaves of a pocket notebook or a pass-case to carry. [0006]
    [0007] Data writing and reading of smart media is conducted by connecting an access device for smart media not only to a digital electronic still camera and a portable information terminal but also to a personal computer etc. or by means of an adapter through a slot of a PC card. [0007]
    [0008] Connecting an access device for external attachment to a personal computer, however, needs a space for the device and a connection code, as well as costing labor for the connection. In addition, it has such a shortcoming as larger electric power consumption than that consumed for an internally provided device. [0008]
    [0009] Moreover, internally providing an access device for smart media has such a drawback as that the size and cost of a main body of a personal computer are increased because an information apparatus such as a personal computer has a limited installation space for internally mounting a device. Also as to a slot for a PC card, since it is scarcely mounted on standard desk-top personal computers for the same reason, use of a PC card requires an access device for the PC card to be added. [0009]
    [0010] Technique directed to solving these conventional problems is disclosed, for example, in Japanese Utility Model Registration No. 3060055. Making use of the fact that in many desk-top personal computers, an FDD drive is installed using an installation space (bay) for a peripheral equipment provided at the front of the main body, the art recited in Japanese Utility Model Registration No. 3060055 proposes a composite FDD device in which a drive for smart media is internally provided in an FDD drive and an insertion slot of a floppy disk and an insertion slot of smart media are provided together on the upper and lower sides. [0010]
    [0011] As described in the foregoing, conventional techniques have the following problems. [0011]
    [0012] Although a dedicated device for accessing smart media is conventionally installed by external attachment to a personal computer or provision within the same, the installation occupies a space for putting the personal computer or a free space within the main body of the personal computer because the dedicated device should be provided together with other disk drive devices. In a case where a dedicated device for accessing a smart media is installed later, it will be difficult to ensure an installation space in an information apparatus such as a personal computer in many cases. [0012]
    [0013] On the other hand, according to the related art disclosed in the above-described Japanese Utility Model Registration No. 3060055, although a drive for smart media is contained in an FDD drive, the FDD drive has a dedicated specification different from that of an ordinary FDD drive. Therefore, it is impossible to replace the FDD drive with an ordinary FDD drive and install the same with ease. Moreover, access is made by inserting smart media one by one to deteriorate efficiency. [0013] SUMMARY OF THE INVENTION

    [0241] The preferred embodiment of the present invention will be discussed hereinafter in detail with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be obvious, however, to those skilled in the art that the present invention may be practiced without these specific details. In other instance, well-known structures are not shown in detail in order to unnecessary obscure the present invention. [0241]
    [0242] In the following, a preferred embodiment of the present invention will be described in detail with reference to the drawings. [0242]
    [0243] FIGS. [0243] 1 to 3 show a structure of a disk drive system according to one embodiment of the present invention. The disk drive system according to the present embodiment is composed of a disk drive 10 capable of conducting reading and writing of both an optical disk such as a CD-ROM and smart media and a media cartridge 20 of the same size as that of an optical disk on which a plurality of smart media can be mounted.
    [0244] As illustrated in FIG. 1, the disk drive [0244] 10 includes, at a tray unit 11 which can be put into and extracted from a main body of a drive 12, a disk rotation shaft 13 of an optical disk such as a CD-ROM, an optical disk access unit 14 for conducting access (write or read) to the optical disk, a smart media access unit 15 for conducting access (write or read) to a smart media 30 mounted on the media cartridge 20, a media recognition sensor 16 for recognizing the smart media 30 mounted on the media cartridge 20 and a media positioning unit 17 for positioning the smart media 20, and a disk keep unit 18.
    [0245] The media cartridge [0245] 20, as illustrated in FIGS. 2 and 3, is structured with a cartridge main body 21 of the same size as that of the optical disk which has a shaft hole 21 a fit in the disk rotation shaft 13 provided at the center, on which smart media attachment units 22 a to 22 d, media positioning claws 23 a to 23 d and media recognition terminals 24 a to 24 d are provided.
    [0246] The smart media attachment units [0246] 22 a to 22 d are formed of concavities on the surface of the media cartridge 20 in which the smart media 30 shown in FIG. 4 is fit in and mounted and whose configuration is adapted to an outer configuration of the smart media 30.
    [0247] The smart media attachment units [0247] 22 a to 22 d are formed at four positions on the media cartridge 20.
    [0248] Here, the smart media [0248] 30 to be attached is formed to have an approximately square outline and provided with a cutout 32 at a part, on the surface of which a contact area 31 is arranged for conducting data access as illustrated in FIG. 4. Structure of this smart media 30 is that commonly used.
    [0249] Provided at a plurality of the parts of the upper edges of the smart media attachment units [0249] 22 a to 22 d are projects 26 for fixing the attached smart media 30 not to be detached. At the time of mounting the smart media 30 on the smart media attachment units 22 a to 22 d, the smart media 30 is pressed so as to climb over the projections 26.
    [0250] Formed at each of the smart media attachment units [0250] 22 a to 22 d is an opening 25 for making the contact area 31 of the attached smart media 30 be exposed to the back side.
    [0251] Data read and write of the smart media [0251] 30 attached to the smart media attachment units 22 a to 22 d is executed as a result of contact of the smart media access unit 15 to the contact area 31 through the opening 25.
    [0252] Provided on the back side of the media cartridge [0252] 20 are the media positioning claws 23 a to 23 d in the proximity and corresponding to the smart media attachment units 22 a to 22 d as shown in FIG. 3. Provided on the back side of the smart media attachment units 22 a to 22 d are the drive recognition terminals 24 a to 24 d, respectively.
    [0253] Detection of any of the media positioning claws [0253] 23 a to 23 d by the media positioning unit 17 provided on the tray unit 11 of the disk drive 10 results in positioning the mounted smart media 30 relative to the smart media access unit 15.
    [0254] The media positioning claw [0254] 23 a to 23 d, as illustrated in FIG. 6, are fixed projecting from the back side of the media cartridge 20. The media positioning unit 17 of the tray unit 11 is structured to have a micro-switch 17 a for sensing a contact by the media positioning claws 23 a to 23 d arranged in a concavity 17 b in which the media positioning claws 23 a to 23 d are fit in.
    [0255] Sensing of any of the drive recognition terminals [0255] 24 a to 24 d by the media recognition sensor 16 of the tray unit 11 leads to recognition of the positioned smart media 30.
    [0256] The drive recognition terminals [0256] 24 a to 24 d are each formed of a combination of terminals, one minus terminal and two plus terminals as illustrated in FIG. 11 and based on a combination of current flows at the time of electrical contact of the drive recognition sensor 16, determination is made which of the smart media 30 of the smart media attachment units 22 a to 22 d is positioned at the smart media access unit 15 and selected.
    [0257] The smart media access unit [0257] 15 is provided to be up and down movable on the tray unit 11. In addition, as shown in FIG. 10, arranged on the upper surface of the access unit 15 is a smart media access terminal 15 a for conducting data writing and reading in contact with the contact area 31 of the smart media 30 and arranged in the vicinity of the same is the media recognition sensor 16.
    [0258] The disk keep unit [0258] 18 of the disk drive 10 is provided in the drive main body 12 so as to be up and down movable and to press the positioned smart media 30 toward the smart media access unit 15 by a predetermined force.
    [0259] Next, description will be made of operation of thus structured disk drive system according to the present embodiment. [0259]
    [0260] When an optical disk or the media cartridge [0260] 20 is set to the tray unit 11 to close the tray unit 11, the optical disk access unit 14 confirms whether the optical disk is inserted or not.
    [0261] Then, an optical disk mode is set when the optical disk is sensed and a smart media mode is set when the same is not sensed. [0261]
    [0262] In the optical disk mode, data write and read to and from the inserted ordinary optical disk is conducted by the optical disk access unit [0262] 14.
    [0263] In the smart media mode, that is, when the media cartridge [0263] 20 is inserted, the system operates in the following manner.
    [0264] First, a rotation speed is set to be a rotation speed for the smart media cartridge [0264] 20 (lower than a speed for an optical disk).
    [0265] At this time, while the micro-switch [0265] 17 a in the media positioning unit 17 is at the off state as illustrated in FIG. 6, when the media cartridge 20 rotes to make the media positioning claws 23 a to 23 d fit in the media positioning unit 17 and come into contact with the micro-switch 17 a, the micro-switch 17 a is turned on as illustrated in FIG. 7.
    [0266] Turn-on of the micro-switch [0266] 17 a stops the rotation of the media cartridge 20. The foregoing operation enables the smart media 30 mounted on the media cartridge 20 to be positioned at the smart media access unit 15 as illustrated in FIG. 8.
    [0267] After the positioning, the smart media access unit [0267] 15 and the disk keep unit 18 move from the opposite sides to fix the smart media 30 being sandwiched together with the media cartridge 20 as illustrated in FIG. 9.
    [0268] At this time, the smart media access terminal [0268] 15 a and the drive recognition sensor 16 shown in FIG. 10 come into electrical contact with the contact area 31 of the smart media 30 and the drive recognition terminals 24 a to 24 d of the media cartridge 20.
    [0269] Coming into contact of the drive recognition sensor [0269] 16 with the drive recognition terminals 24 a to 24 d leads to determination which of the smart media 30 of the smart media attachment units 22 a to 22 d is positioned and selected according to a combination of electric currents at the time of contact.
    [0270] Then, data write and read to and from the smart media [0270] 30 is conducted by the smart media access terminal 15 a of the smart media access unit 15.
    [0271] In addition, in a case of accessing other smart media [0271] 30, rotate the media cartridge 20 to position other smart media 30 mounted on other smart media attachment units 22 a to 22 d and to make access in the same manner.
    [0272] The foregoing mechanism realizes a smart media changer capable of simultaneously accessing four smart media [0272] 30.
    [0273] Although in the above-described embodiment, determination which of the smart media [0273] 30 of the smart media attachment units 22 a to 22 d is positioned is made by electrical contact of the drive recognition sensor 16 with the drive recognition terminals 24 a to 24 d, other arrangement is possible as shown in FIG. 12 in which a drive recognition projection unit 27 made up of a plurality of projects is provided on the side of the media cartridge 20 in place of the drive recognition terminals and a contact sensor 16 a for identifying a combination of the drive recognition projects 27 by mechanical contact is provided on the side of the disk drive 10.
    [0274] Further possible is an arrangement as illustrated in FIG. 13 in which a drive recognition pattern [0274] 28 such as a bar code is provided on the side of the media cartridge 20 in place of the drive recognition terminal and an optical sensor 16 b for optically reading and identifying the drive recognition pattern 28 is provided on the side of the disk drive 10. Other than a pattern such as a bar code, characters and the like can be optically read and recognized.
    [0275] Moreover, replacing the openings of the smart media attachment units [0275] 22 a to 22 d of the media cartridge 20 by openings 25 a through which not the part of the contact area 31 but the whole of the smart media 30 is exposed enables detachment of the smart media 30 from the smart media attachment units 22 a to 22 d without direct contact of a finger with the contact area 31.
    [0276] In addition, although in the above-described embodiment, the smart media access unit [0276] 15 is provided on the tray unit 11 of the disk drive 10, it can be provided not on the tray unit 11 but on the side of the drive main body 12.
    [0277] The system is applicable not only to a disk drive of a tray type but also to that of a clamshell type. [0277]
    [0278] Applicable as the disk drive [0278] 10 are such drives as a CD-ROM drive, a CD-R drive, a CD-R/RW drive, a DVD-ROM drive, a DVD-RAM drive, and a PD drive.
    [0279] Furthermore, although in the above-described embodiment, the number of smart media which can be set in the media cartridge [0279] 20 is four, it can be not more than four or not less than four if physically allowed.
    [0280] As described in the foregoing, according to the disk drive system of the present invention, incorporation of a smart media reading and writing function into a disk drive allows a space for the disk drive to make access to both an optical disk media and the smart media, thereby enabling reduction of a device installation space in an information apparatus such as a personal computer. [0280]
    [0281] In addition, since the function of the smart media changer is realized by the arrangement in which a plurality of smart media are mounted on a smart media cartridge, the plurality of smart media can be handled simultaneously to enable efficient use. [0281]
    [0282] Although the invention has been illustrated and described with respect to exemplary embodiment thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions and additions may be made therein and thereto, without departing from the spirit and scope of the present invention. Therefore, the present invention should not be understood as limited to the specific embodiment set out above but to include all possible embodiments which can be embodies within a scope encompassed and equivalents thereof with respect to the feature set out in the appended claims.
