摘要： A cartridge for housing a disk-shaped information recording medium to be inserted in a recording and reproduction apparatus. The cartridge includes a first case for enclosing a first half of the disk and a second case for enclosing a second half of the disk. The first and second cases are movable into and out of contact with each other along a pair of disk support members. When the first and second cases are in contact with each other the disk is completely enclosed and protected from contamination. Upon insertion in the recording and reproduction apparatus, the first and second cases are automatically separated by a predetermined distance to expose a radial portion of the disk for recording and reproduction.

摘要： An optical disk with a recording layer formed on the inner surface of a protective plate has data which is read out upon irradiation of a laser beam. A substrate supports the protective plate such that the recording layer opposes the substrate and a space is formed therebetween. The spacer is sandwiched between the protective plate and the substrate so as to couple them. The spacer is an elastically deformable member. Therefore, when the protective plate expands or contracts relative to the substrate, due to deformation of the spacer, excessive force does not affect the recording medium. Warp, wave or damage to the disk due to expansion/contraction of the protective plate or substrate can be prevented, thereby allowing stable data processing.
摘要翻译：具有形成在保护板的内表面上的记录层的光盘具有在照射激光束时读出的数据。基板支撑保护板，使得记录层与基板相对并在其间形成空间。间隔件被夹在保护板和基板之间以便联接它们。间隔件是可弹性变形的构件。因此，当保护板相对于基板膨胀或收缩时，由于间隔件的变形，过大的力不影响记录介质。可以防止由于保护板或基板的膨胀/收缩导致的盘，波或损坏，从而使数据处理稳定。

摘要： An information memory medium (10) includes disk-shaped substrates (30a, 30b) and recording layers (32a, 32b). It also has a centering member (38a, 38b) whose coefficient of thermal expansion resembles that of the substrates (30a, 30b). Two flat magnetic members (40a, 40b) are situated in annular depressions (68a, 68b) provided in the centering member. The annular depressions are larger than the magnetic members so that differences in thermal expansion can be absorbed.

摘要： A radiation-sensitive record disc is disclosed having a first disc and a second disc coaxially positioned adjacent the first disc to reinforce the first disc. A first spacer is positioned between the first and second discs for fixedly connecting the discs together and to form an air space between the discs. A recording layer is formed on one surface of the first or second discs within the air space. A second spacer is radially displaced from the first spacer, and positioned between the first and second discs. This second spacer enables the discs to move relative to each other in a radial direction in response to expansion or contraction of at least one of the discs due to changes in temperature, humiduty, atmospheric pressure, etc. In the preferred embodiment the first spacer comprises projections on the inner surface of the second disc, and the second spacer comprises an annular ring which slidably engages a projection on the outer peripheral surface of the second disc member.

摘要： An information processing apparatus includes a casing having a loading slot through which a cartridge is inserted into and taken out of the casing. In the casing is arranged an information processing unit which has a drive base mechanism for information processing with an optical disc in the cartridge and a loading mechanism for loading and unloading the cartridge onto and from the drive base mechanism. The processing unit is elastically supported in the casing by a vibration insulating mechanism so that vibrations acting on the unit are absorbed. While a cartridge is being inserted into or taken out of the casing, the processing unit is locked at a specified position by a locking mechanism. When the cartridge is completely loaded onto the drive base mechanism, the locking mechanism releases the locked state of the unit.

摘要： An optical disk comprising a disk-like body having two base plates made of synthetic resin and two recording layers formed on the base plates, respectively. The body is formed by bonding the base plates, with a spacer interposed therebetween, such that the recording layers face each other. The disk further comprises two centering members, each projecting from the surface of the center portion of each base plate. Each centering member is made of synthetic resin, and one magnetic member is mounted on the centering member. The centering member is inserted in a hole formed in the center portion of the body. The centering member has a center hole defining the center of rotation of the body, and also a recess for holding the magnetic member. Four through-holes are formed in the bottom of the recess. The magnetic member has four projections and is held in the recess, with the projections inserted into the through-holes of the bottom of the recess. Since the optical disk has magnetic members, one on each surface, it can be attracted to the turntable of a drive mechanism by means of the magnetic force exerted by the magnet fitted in the recess formed in the surface of the turntable.
