摘要： A detecting system for detecting a rotation angle of a deflecting mirror is disclosed. The detecting system is provided with a laser diode, an objective lens, and a deflection mirror therebetween. The deflection mirror is rotatable about a predetermined rotation axis to change the position, on an optical disc, at which a laser beam emitted by the laser diode is incident. Further, a beam splitter is provided to split the light beam into a first beam directed to the optical disc via the deflection mirror, and a second beam that is directed to a reflection surface of the deflection mirror. The second beam reflected by the reflection member is not directed to the optical disc but received by a detector which determines the rotation angle of the deflection mirror in accordance with the received second beam.

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.
摘要翻译：利用磁场调制记录方法的磁光盘驱动系统具有用于在其中容纳磁光盘的盘盒，可插入到系统外壳中的磁头和用于将信息写入磁光的系统外壳中的磁头磁盘保持在磁盘盒中。盘盒由凸轮槽和凸轮销引导，用于当插入系统壳体时在第一卸载位置和第一装载位置之间移动。磁头由凸轮槽和凸轮销引导，用于在远离盘盒的第二卸载位置和靠近盘盒的第二装载位置之间移动。通常在张力弹簧的偏压下，磁头被迫从第二装载位置向第二卸载位置移动。当磁光盘驱动系统的主电源接通时，锁定臂被电磁铁吸引，以将磁头锁定在第二装载位置。当电磁体被断电时，锁定臂被释放，在拉伸弹簧的偏压下使磁头解锁，从第二装载位置向第二卸载位置移动到第二卸载位置。

摘要： A position detecting mechanism, adapted to be positioned in a device having an optical head arranged to be movable in tracking direction, for detecting the position of the optical head in the tracking direction. A pair of light transmitting members for transmitting light toward the optical head, reflecting plate, provided on the optical head extending along the tracking direction, for reflecting the light transmitted from the pair of light transmitting members at the edge portions thereof along the tacking direction, and a pair of light receiving members for receiving the light reflected by the reflecting plate and outputting signals corresponding to amounts of light received by the light receiving members are provided. The pair of light transmitting members and the pair of light receiving members are arranged in a row along a predetermined line in parallel to the tracking direction. Therefore, the position of the optical head along the tracking direction is not erroneously detected even when the reflecting plate is moved in the focusing direction.
