Apparatus and method for optical disk drive signal processing

摘要

The present invention describes an apparatus and method for optical disk drive signal processing. For improving the bandwidth for signal transmitting between an optical disk drive (ODD) controller and an optical pick-up unit (OPU) via a flexible cable, a physical address pre-processing unit is mounted on the optical pick-up unit of a Optical disk drive. The long settling time problem conventionally due to a voltage change in the writing process can be resolved. The apparatus and method extract the physical address in the high-writing process of the Optical disk drive.
