A flexible disk drive has the configuration of a type-2 card for use in a personal computer or other information processing apparatus. The flexible disk drive includes a cabinet for insertion into a card slot in the information processing apparatus, a mechanism for inserting and ejecting a recording medium cartridge containing a recording medium, a head for accessing the recording medium, a head drive actuator for moving the head, a recording medium drive actuator for driving the recording medium, a position device for positioning the recording medium in a predetermined position, and a drive force transfer mechanism for transferring the driving force of the recording medium drive actuator to the recording medium. The components of the flexible disk drive have thin profiles to achieve the form factor of the type-2 card.

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.

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.

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.
