摘要:
A card which is readable by a card reader is provided, in which an insertion direction of the card relative to the card reader, and a transactional function of the card can be easily recognized by visually handicapped users. In particular, the card is made up of a card body having a machine readable portion thereon which is readable by the card reader only when the card is inserted in a predetermined direction, and further includes an indication formed in the card body. Such an indication enables a user to tactually recognize the insertion direction with respect to the card reader, as well as the purpose or transactional function of the card, merely by means of touching the card with one's fingers. In a first mode of the invention, the indication is provided by a depression or a projection, whereas according to other modes, cutouts, or a slanted side edge of the card body may provide the desired indication of direction or function of the card. A promotional card having a detachable section is also proposed in which the cutout is formed upon detachment of the detachable section. A set of cards may also be provided, each having a different transaction functional, as indicated by different indications, or positions of indications, on the respective cards.
摘要:
In an automatic medium changing apparatus capable of storing a multiplicity of optical disks, the control parameters required for the drive control system of a drive unit for recording-reproducing are automatically regulated for all the combinations of the existing drive units and all the media held. The resulting values of the control parameters are stored in a control unit of the automatic medium changing apparatus and the apparatus is controlled by the corresponding control parameters transferred from the control unit at the time of processing the medium.
摘要:
A method and apparatus for recording information on an information recording medium and/or reproducing information from the recording medium. Probes for recording and/or reproducing information and a support for supporting the probes are arranged so that the probes are positioned to face the information recording medium. The support and the information recording medium are relatively moved by sliding on sliding surfaces thereof. The distance between the support and the recording medium is roughly set by projections formed between the support and the recording medium, and is finely adjusted during operation by a mechanism for moving the probes.

Reference heads for use in flexible data storage cards are disclosed. In one embodiment, a reference head includes a planar card surface for attachment to an interior housing surface of a flexible data storage card, and a non-planar reference surface opposite the planar card surface. In one embodiment, a non-symmetric reference head for use in a flexible data storage card housing a rotatable media disc includes a body defining a first planar surface opposite an optically smooth second planar surface, and a location feature formed in the body. In this regard, the location feature is configured to reproducibly orient the optically smooth second planar surface toward the rotatable media disc.

An optical disk adapter can position a deformed CD at a predetermined position in a disk-transferring tray by a very simple operation, and is simple in structure and easy in manufacture. At the central portion of an adapter main body (1a) having an external periphery with the same diameter as a 12 cm-CD, a positioning true circular central aperture (2) in which a square CD (C1) with an 8 cm-diagonal length can be fitted in a non-restricted state is provided. The center of this positioning true central aperture (2) is concentric with the center of the adapter main body (1a). The adapter main body (1a) is provided with a rotation prevention protrusion (3) against the disk-transferring tray (71) at the lower surface thereof and a disk clamper passing dented portion (4) at the upper surface thereof. The rotation prevention protrusion (3) has a thickness which can serve as an optical disk entering prevention protruded portion, and is provided with a protrusion (5) which comes into contact with a chassis (82) of a driving unit (81) in a cabinet at a lower surface thereof, whereby the rear end of the adapter is lifted from the 12 cm-disk placing dented portion (72) when the driving unit (81) is lifted.

A credit card-sized card having a rotating magnetic memory therein is disclosed. The card is provided using a laminated structure in which a stainless steel, plastic sandwich structure is employed. An opening in the plastic layer provides space for the rotating magnetic disk. Data is written to or read from the disk by positioning heads from an external system into openings in the external surface of the card. When the card is not engaged in a reader, a shutter covers the openings.

摘要:
The present invention is a two-part optical disk with a nested, centrally positioned removable disk in the original configuration the disks comprise two disks removably joined together so as to enable both disks to be readable with a computer disk drive. The two-part optical disk is further configured so as to be separable into independent disks. After separation of the two disks, only data on the formerly nested inner optical disk continues to be accessible by a computer disk drive. Data on the formerly surrounding outer disk is no longer accessible by a computer disk drive The two-part optical disk has large data storage capability but with separation offers all the advantages of the small disk format: convenient storability, portability and support functionality.
摘要:
Apparatus is described for reading data from or writing data onto a credit card-sized storage media containing a rotating magnetic memory. The reader includes a spindle motor and an arm with a magnetic head position thereon, as well as integrated circuits for controlling its operation. The reader preferably complies with standards for PCMCIA cards, enabling the reader to be inserted into the host system such as a personal computer or a laptop for use.
