摘要： A small and thin storage device that can be substituted for IC memory card is disclosed. When the recording medium cartridge is inserted into the frame of the storage device, a slide member in a hub moves parallel to the frame and retracts a shaft under restriction of a restriction member provided in the recording medium cartridge so that the hub and the shaft engage. When the recording medium cartridge is ejected from the frame, the slide member moves parallel to the frame and the shaft under restriction of the restriction member so as to release the engagement of the shaft and the hub.

摘要： A recording medium cartridge includes a disk-shaped recording medium and a case housing the recording medium. A window is provided in the case to expose a portion of the recording medium. A shutter is provided on the case to close and expose the window. A latch is movable in a direction perpendicular to the direction of relative movement of the shutter and is linked to the shutter by a band such that movement of the band causes the shutter to selectively close or expose the window. In one embodiment, the recording medium cartridge has a non-zero thickness equal to or less than approximately 2.0 mm.

摘要： A mechanism for a loading/unloading read and/or write head of a disk drive apparatus against a magnetic disk, includes a lifter which bends a suspension supporting the read and/or write head. The suspension is bent by moving a lifter up responsive to movement of the read and/or write head to detach the read and/or write head retained on a tip of the suspension from the magnetic disk by a given distance, thereby a high shock resistance is obtained.

摘要： An object of the present invention is to provide a low cost, high performance, thin structure rotary motor for driving medium used in magnetic disk drive unit, optical disk drive unit or the like, in order to improve the productivity of terminating processing and the reliability of the coils. Magnetic materials which are divided to a plurality of blocks or divided corresponding to respective magnetic pole teeth are connected by means of thin portions. The respective magnetic pole teeth are wound continuously with wire without cutting the wire at the positions in which the thin portions are connected. When a stator is assembled, a plurality of blocks or magnetic pole teeth are disposed on a substrate by separating or bending the thin portions.

摘要： A retract mechanism for a magnetic head which can read from and/or write to a disk, the mechanism includes a spring arm which supports the head and urges the head toward the disk. The spring arm includes a cam follower which rides along the surface of the cam, which has two parallel horizontal surfaces and two incline surfaces. The spring arm is moved by an actuator in a radial direction along the disk. When the spring arm is moved radially away from the center of the disk, the cam urges the spring arm upwardly, thereby lifting the head up and away from the disk. As the spring arm continues to move radially away from the center of the disk, the cam guides the spring arm such that the head rests safely on a landing platform.
