    摘要： A magnetic circuit for a voice coil motor of flat-coil type used with a magnetic device is disclosed. The magnetic circuit is intended to flatten the torque constant curve for swinging the rotor of the voice coil motor while at the same time preventing the torque constant from decreasing. For this purpose, the magnetic circuit comprises an upper yoke and a lower yoke opposed to a flat coil arranged on the rotor, a pair of side yokes for coupling the upper and lower yokes to each other at the ends thereof, and a magnet arranged on the lower yoke. The magnet is shaped arcuate so that the width in the neighborhood of each end thereof in the direction of motion of the flat coil is larger than a standard width and smaller than the standard width in the portions of the magnet between each end and the central portion thereof.

    摘要： Vibrations in a magnetic head assembly equipped with a magnetic head, caused by the effects of the flow of air arising from the high-speed rotation of a magnetic disk, can be suppressed by affixing a damping material to the magnetic head assembly. As a result, accurate positioning is possible with high reliability, the frequency of occurrence of errors during data recording and playback can be suppressed, high data transfer rates can be maintained, and high recording densities for a magnetic disk device can be realized.

    摘要： A disk drive includes a casing for enclosing at least a disk and a head. Rectification walls are disposed at corners of the casing. The walls serve to rectify an air stream generated by rotation of the disk at the periphery of the rotating disk. A bypass is defined between the side wall of the casing and at least one rectification wall. A filter is disposed in the bypass for catching dust in the air stream. A parameter d/L, where d is the width of an entrance of the bypass and L is the length of the comer along the periphery of the disk, is determined so that vibration of the rotating disk is equal to or less than an admissible value estimated from a tracking error margin. The tracking error margin is estimated from a track pitch on the disk. Reliable positioning of the head with respect to the disk can be achieved with the present invention.

    摘要： A miniaturized optical disc memory is receivable in a slot, of about 17 mm height, normally accommodating a floppy disc drive. A base includes a base plate with integral, peripheral sidewalls and an internal lateral partition wall which define a cartridge receiving slot on the upper surface of the base plate. First and second support plates extend from the partition wall to the rear peripheral sidewall of the base and define respective, first and second upper mounting surfaces and lower first and second cavities respectively receiving an ejection motor and a fixed optical system, individual optical components being mounted and aligned on integral, precision machined blocks in the second cavity for transmitting a laser beam and receiving a reflected beam along a central, longitudinal optical axis beneath the base plate. A first base plate aperture accommodates a lens carriage driven in reciprocating motion along the axis for receiving and redirecting the laser beam vertically for scanning an optical disc and receiving a reflected beam and redirecting same to the fixed optical system. The movable optical system is locked in a rest position and is released by insertion of a cartridge to permit scanning movement thereof. A disc drive unit is mounted beneath the base plate for reciprocating vertical movement through a second aperture therein to a raised position for engaging and driving, in rotation, an optical disc of a cartridge inserted into the apparatus and to a lowered position for releasing the cartridge and permitting ejection thereof.
