ABSTRACT:
An optical disk apparatus for effecting at least one of recording of information and reproduction of information by use of a light beam is disclosed. The apparatus include an optical carriage having at least an optical system including an objective lens for converging a light beam onto a recording medium and a tracking/focusing actuator for moving the objective lens along a tracking/focusing direction of the recording medium. The apparatus further includes a linear motor for moving the optical head carriage radially of the recording medium and a wiring member extending from the tracking/focusing actuator and the linear motor. A fixing device is further provided so as to fix the wiring member to suppress movement of the optical head carriage in a case of an inoperative condition of the apparatus, such as during transportation.
