The present invention provides a disk drive apparatus for recording and/or playing back a signal onto and/or from a disk-shaped recording medium. The disk drive apparatus has a configuration comprising a head arm for supporting a magnetic head. The head arm is provided with an arm base made of a rigid material and a suspension implemented by a plate spring. Since in the configuration of the disk drive apparatus provided by the present invention includes a head arm which is provided with an arm base made of a rigid material and a suspension implemented by a plate spring, the length of the suspension can be shortened and the positional precision of the magnetic head can be assured with a high degree of reliability.

A disk drive wherein a head raising and lowering arm is rotated around a pivot shaft of a slide plate by a cam action due to a cam groove of the head raising and lowering arm and a fixed guide shaft when the head raising and lowering arm is inserted in a head suspension by the slide plate, so that the head performs a soft landing from a head unloading position to a head loading position on a floppy disk.

An auto-loading system for recording medium cartridges is provided which permits the simple and reliable operation of rotating the recording medium cartridges between a magazine and a drive. The auto-loading system has a cartridge tray of an elevator which is moved upward and downward between a cartridge port of the drive and a cartridge insertion port and a cartridge ejection port of the magazine within an autoloader body so that a plurality of recording medium cartridges are rotated between the magazine and the drive by the operation of ejecting the recording medium cartridges into the cartridge tray from the cartridge ejection port of the magazine by a first cartridge ejecting mechanism and the operation of ejecting the recording medium cartridges into the cartridge port of the drive or the cartridge insertion port of the magazine from the cartridge tray by a second cartridge ejecting mechanism.

A disc drive includes a cartridge holder formed of a single piece of sheet metal which cooperates with a slide plate which is similarly formed of a single piece of sheet metal. The sides of inclined guide slots formed in side walls of the slide plate are parallel and serve to guide horizontally projecting flange-like guide members of the cartridge holder. A single piece disc shutter control arm is pivotally mounted in the cartridge holder and motivated by the force which moves the disc cartridge into the disc holder in a manner which opens the disc cartridge shutter. The chuck yoke of the turntable is provided with an inertia increasing annular member. A head is mounted on a pivotal head arm which is operatively connected with the cartridge holder in a manner to be pivoted up and down therewith. A head carriage is released and operatively connected with a motor upon the cartridge holder being lowered past the level whereat the disc hub of the disc in the disc cartridge is placed on the chuck yoke and the head is placed on the upper surface of the disc.

A disk drive apparatus has a cassette holder into which a disk cassette is inserted. The cassette holder is obliquely reciprocated between a cassette insert position and a cassette load position as guided by a plurality of inclined guides provided on a pair of side plates of a chassis. In ejecting the disk cassette, the cassette holder is moved directly by an eject lever against a biasing member. Accordingly, it is unnecessary to employ a slide plate for reciprocating the cassette holder.
