Abstract:
An optical disk, comprising a transparent synthetic resin disk substrate (1) having a center hole for chucking (5) and forming a clamping area (6) around the center hole (5) and an extensible or an inextensible film for label print surface formation (10) disposed on the upper surface of the disk substrate (1) so as to close the center hole for chucking (5), wherein, when the film (10) is extensible, at least the area (10a) of the film corresponding to the center hole for chucking is extended and retracted as a disk chuck (84) for chucking the optical disk is inserted into and extracted from the center hole for chucking (5) and, when the film (10) is inextensible, a cutout (8) is formed in the area of the film corresponding to the center hole for chucking (5), and the cutout is opened and closed as the disk chuck (84) for chucking the optical disk is inserted into and extracted from the center hole for chucking (5).
Abstract:
A device of the same general physical size and shape as a standard audio cassette tape, but which accepts digital information from any of a variety of sources - including for example: Internet transmission, a digital computer, or memory cards (especially digital memory cards) - and plays this digital information through any, for example, standard audio tape cassette player. The device operates by converting the digital representation of the sound into magnetic signals which are presented to the read/write head of the cassette player equipment. The device allows the user of the cassette player to regulate the audio playback using conventional equipment controls such as: START, STOP, REWIND, FAST REWIND, FORWARD, FAST FORWARD, etc. In one exemplary implementation, the device has the same general physical dimensions of a standard audio cassette; at least one digital processor; and a slot into which electronic media such as, for example, memory cards, smart cards having a processor and a memory embodied thereon and other memory media may be inserted. The device also includes user input control buttons, a display and a headphone jack all mounted in the case of the cassette device such that they are substantially flush with the case and will not interfere with the use in a cassette player. The user can use the cassette device in a cassette player and also use the cassette device as a portable and free standing, digital audio player.

Numerous sensors detect changes in at least one of the tape equipment mechanisms in the audio cassette emulator. Various cryptographic techniques are described for protecting the unauthorized distribution of audio information.
Abstract:
A convey apparatus for conveying a storage medium using a solid memory into and out of a recording and/or reproduction apparatus, wherein a holder (52) for holding an inserted storage medium (1) is moved between an eject position where a recording medium (1) is ejected and a loading position where the recording medium is loaded, a rocking lever (93) moved in association with the movement of the holder (52) and rocked is selectively engaged with a chassis (71) or the holder (52), a first biasing member (94) moves/biases the holder (52) in the opposite direction to the storage medium insertion direction and accumulates a biasing force for ejection direction, and a second biasing member (95) biases the holder (52) in the storage medium insertion direction, so that the holder (52) is switched between the movement in the storage medium insertion direction and the movement in the eject direction.

Abstract:
Apparatus and method wherein a credit card sized memory card (16) having a magnetic storage medium (18) thereon can be inserted into an operative position adjacent to a read/write head (24), and the card and head can be moved relative to each other to permit the head to read data from or to write data on the magnetic medium of the memory card. In a first embodiment, a disk form (12) is provided like a hard disk but with a cut out portion or opening (14) therein into which the memory card is insertable. The disk form can then be rotated so that the magnetic medium on the card can be moved past the read/write head movable radially of the central axis (21) of the disk form. In another embodiment the memory card (102) is movable into a fixed operative position adjacent to a read/write head (106) and the head is movable radially as well as circumferentially so that the head and memory card are movable relative to each other in two degrees of freedom.
Abstract:
An educational apparatus for reproducing visible information drawn on the front surface of a magnetic sheet (2) and audio information related to the visible information and recorded on the back of the magnetic sheet (2), via a head (5) provided on a turntable (4), the magnetic sheet (2) being inserted into the apparatus in the direction of an arrow and then positioned in the apparatus. A roller (8) is pivotally secured to the lower portion of a pin (3) for positioning the magnetic sheet (2) so that the pin (3) is entirely urged upwardly by a spring (9). High and low cam surfaces (6a') and (6a'') are concentrically provided under the turntable (4). When the turntable (4) is stopped, the roller (8) makes contact with the cam surface (6a') to depress the pin (3) so as to thus readily insert the magnetic sheet (2). When the turntable (4) starts turning, the roller (8) is separated from the cam surface (6a') to cause the pin (3) to be moved upwardly so as to exactly position the magnetic sheet (2) at a conical head (3a) of the pin (3). Idlers (16), (17) are interposed among a motor (13), a flywheel (14) and the turntable (4) to equalize the turning of the turntable (4) at constant speed.
Abstract:
An adapter (A1) is made of a synthetic resin and includes an annular frame (1) having an external diameter of 12 cm, a disc reception unit (2) connected to the inner bottom of the frame (1), and a pair of disc pressing units (3, 3) connected to the inner top of the frame. The disc reception unit (2) has a circular cut (4) for exposing the disc information recording area to the disc player optical reading device. On the lower surface of the disc pressing units (3), there is provided a disc contact protrusion (7) formed with a protrusion height increasing little by little in the disc rotation direction Y. This adapter (A1) can reliably and easily mount a non-circular disc of a slightly different size.
