A magnetic head carriage moves a magnetic head between a standby position and a head application position. An optical head carriage supports an optical head to read at least identification tracks of a magneto-optical disk. A synchronizing device synchronizes linear positions of the magnetic head carriage and the optical head carriage, such that the magnetic head carriage is proximate an outermost position of the magnetic head carriage and the optical head carriage is proximate an outermost position of the optical head carriage when the synchronizing device synchronizes the linear positions of the magnetic head carriage and the optical head carriage.

摘要： A magneto-optical disk drive system, utilizing a magnetic field modulation recording method, has a disk cartridge for housing a magneto-optical disk therein and insertable into a system housing and a magnetic head in the system housing for writing information on the magneto-optical disk held in the disk cartridge. The disk cartridge is guided by cam grooves and cam pins for movement between a first unloading position and a first loading position when inserted in the system housing. The magnetic head is guided by cam grooves and cam pins for movement between a second unloading position remote from the disk cartridge and a second loading position close to the disk cartridge. The magnetic head is normally urged to move from the second loading position toward the second unloading position under the bias of a tension spring. A lock arm is attracted by an electromagnet to lock the magnetic head in the second loading position when the main power supply of the magneto-optical disk drive system is turned on. When the electromagnet is de-energized, the lock arm is released, unlocking the magnetic head to move from the second loading position toward the second unloading position toward the second unloading position under the bias of the tension spring.

摘要： A disk cartridge loading system for a disk drive. The loading system includes a disk cartridge holder, a drawing mechanism, a draw-in sensor, a loading sensor, and a controller. The drawing mechanism engages a partially inserted disk cartridge to fully draw the disk cartridge into the disk drive, so that the disk cartridge is accommodated in a disk cartridge holder. A holder moving mechanism moves the disk cartridge holder to a loading position, so that at least one of a data reading operation and a data writing operation can be performed. A draw-in sensor is provided to detect the partial insertion of the disk cartridge, while a loading sensor detects when the disk cartridge is located at the loading position. A control unit controls the drawing mechanism and the holder moving mechanism, based on a first signal produced by the draw-in sensor and a second signal produced by the loading sensor.

摘要： A magneto-optical disc apparatus, including a holder which holds a magneto-optical disc cartridge and which is movable between a loaded position, in which the holder is close to an optical head, and an unloaded position, in which the holder is apart from the optical head. The magneto-optical disc apparatus further includes a magnetic head which is movable between an initial position, in which the magnetic head is apart form the optical head, and an effective position, in which the magnetic head is close to the magneto-optical disc and can apply a magnetic field to the magneto-optical disc to record and/or play-back data. The magneto-optical disc apparatus features a mechanism for guiding the holder between the loaded position and the unloaded position. The apparatus further features a mechanism for guiding the magnetic head between the effective position and the initial position, and through an intermediate step position between the effective and initial positions.

摘要： A recording/reproducing apparatus incorporates a beam splitter arrangement that directs stray reflected light away from the incident and exit paths. The beam splitter is arranged such that refracting surfaces are angled away from a 45 degree angle by an amount corresponding to a refracted angle of an incident beam. The entire beam splitter is arranged in the recording/reproducing apparatus such that the refracted beam is refracted by a predetermined angle based on the known refractive index of the beam splitter prisms and the orientation of the beam splitter.
