摘要： An optical disc drive is provided with a light source unit that emits a collimated light beam, and a carriage mounting an objective lens for converging the collimated light beam on a recording surface of an optical disc. The carriage is movable in a direction traversing data tracks of the optical disc. The optical disc drive is further provided with a lens actuator mounted on the carriage. The lens actuator has a movable unit capable of moving the objective lens in first and second directions, independently. The first direction is a direction of an optical axis of the objective lens, and the second direction is a direction on a plane parallel to the data recording surface of the optical disc. A magnetic head is mounted on the movable unit of the lens actuator. The magnetic head is capable of applying a magnetic field onto the data recording surface of the optical disc when data is to be recorded on the optical disc. A positional relationship between the objective lens and the magnetic head is substantially constant regardless of the moving amount of the movable unit in the first and second directions.

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 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.
