Abstract: An optical recording medium is provided which has a substrate and a signal recording layer provided on the substrate and in which an information signal is recorded in the form of microscopic pits. A light beam is focused on the signal recording layer and some change of the light beam carried by a return light from the signal recording layer is detected to read the information signal recorded on the signal recording layer. The optical recording medium has a diameter of 65 mm or less and a thickness of 0.4 to 0.7 mm. An information signal recording area extends outwardly from a radial position of 12.5 mm or less from the center of the medium. The ratio in area between the information signal recording area and non-signal recording area is 3.4 or more. The storage capacity of this medium is 2 gigabytes or more. The optical recording medium has formed at the center thereof a center hole around which an annular table-abutment convexing to one side of the medium is formed. A magnetic-clamping hub is installed in the center hole and thus the medium is magnetically clamped to a rotation driving mechanism of an optical recording and/or reproducing apparatus. The compactness and high density of recording of the optical recording medium will contribute greatly to a further compact structure of a recording and/or reproducing apparatus in which the medium is to be used.

Abstract: There are disclosed recording/reproducing devices for use with computers and particularly for recording or reproducing desired information on or from recording mediums like floppy disks, the devices being miniaturized and reduced in thickness for adapting themselves to the miniaturized computers of nowadays. The reduction in device thickness involves the use of a small-sized rare earth group magnet and neodymium ferrous boron which have good magnetic properties as rotor magnets of disk and carriage driving motors; or alternatively planar superpositions are avoided when placing the disk driving motor and the carriage or a carriage guide shaft and a circuit board. The thinned recording/reproducing devices contribute to diminishment of a space for accommodating the computer to meet a demand for miniaturization thereof. A plurality of miniaturized recording/reproducing devices of the invention can be set in the existing space for placement.

Abstract: A disk chucking mechanism for selectively chucking floppy disks onto a turntable has a strong neodym first magnet provided on an inner periphery of the turntable so as to attract a first hub and a second hub, and a weaker ferrite second magnet positioned low on an outer periphery of the turntable opposite a projection formed on the second hub and attracting only this second hub. By using these two magnets a satisfactory clamping of the floppy disks to the turntable can be achieved even when both lower grade (ordinary) and upper grade (high-density) floppy disks are loaded and driven.

Abstract: A movable platform is mounted on opposing guide rails within a disk drive. A head actuator and spindle motor are mounted on the movable platform. The platform moves on the guide rails from a forward position to a rearward position upon insertion of a disk cartridge into the disk drive. As the platform moves toward the rearward position, the elevation of the platform changes in order to bring the spindle motor into engagement with the hub of the disk cartridge. A latch member is pivotally mounted on one of the guide rails for latching the platform in its forward position when the disk drive is not in use.

Abstract: A disk drive for use with a flexible magnetic disk having a sheet metal hub with a central hole and an eccentric slot formed therein. The disk drive has a turntable on which the disk is to be placed for joint rotation therewith. The turntable has a spindle disposed centrally for centering engagement in the central hole in the disk, and a drive pin disposed eccentrically on the turntable for driving engagement in the eccentric slot. Erected on the free end of a lever which is pivotally mounted to the turntable, the drive pin is biased to travel substantially radially outwardly of the turntable so that the disk may be engaged by the spindle and the drive pin without looseness. Since the data storage disk when first loaded on the turntable rests slantingly thereon, with the drive pin butting endwise against the disk, until the drive pin becomes engaged in the disk slot with the rotation of the turntable, the support lever is formed to include a constricted neck portion intermediate the opposite ends thereof. The neck portion is capable of torsional deflection to permit the drive pin to tilt radially inwardly of the turntable into right angular relationship with the data storage disk resting slantingly on the turntable, whereby the drive pin is smoothly admitted into the disk slot upon rotation of the turntable.

Abstract: An arrangement for inserting and extracting a recorded medium in which a movable slidable member is slidable in directions into and out of said stationary housing member. The slidable member is provided with two nose-shaped elements that are spaced from one another. A single switch mounted on the stationary housing member is actuated by the nose-shaped elements when the slidable member moves in-and-out of the stationary housing member. The in-and-out motion of the slidable member is made dependent on the states of the single switch.
