METHOD AND APPARATUS FOR MOVING AN OPTICAL PROCESSING UNIT IN AN OPTICAL DISC DRIVE

摘要

A method and related apparatus used for moving an optical processing unit (OPU) of an optical disc drive toward an initial position before the optical disc drive accesses optical disc data is disclosed. The method includes: providing a driving force to drive the OPU; determining whether or not the OPU starts to move; and increasing the driving force if the OPU does not move yet. Further, once the OPU is moving, speed control is maintained through use of a controller and a detecting device.
