摘要： A galvano mirror unit including a galvano mirror, a mirror holder holding the galvano mirror, and a hinge member which swingably supports the mirror holder. The hinge member includes a support plate and a base. The support plate has a thinner portion extending across the support plate in one direction, so that the thinner portion divides the support plate into first and second sections. The first section is fixed to the mirror holder, while the second section is supported by the base. The mirror holder is swingable about the thinner portion, due to an elastic deformation of the thinner portion.

摘要： There is provided a head of an optical data recording/reproducing device. The head is provided with a laser source, a deflector, a relay optical system and an objective lens system. The laser beam emitted by the laser source is incident on the objective lens system via the deflector and the relay optical system. The head is further provided with a rotation angle detecting system which includes a beam splitter provided between first and second relay lenses of the relay lens system, and a detector. The beam splitter divides the incident beam into a first beam directed to the second relay lens and a second beam directed to the detector. The detector has two light receiving areas, and a controller determines an amount of rotation of the deflector based on the amounts of light received by the two light receiving areas.

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.
