DATA PROCESSOR AND DATA PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a data processor which is capable of enhancing data processing ability while reducing electric power consumption as far as possible. SOLUTION: In the data processor 1, a head 3 for a pickup reads data out of a memory medium 2. This data is transferred by a plurality of bit in a parallel state in synchronization with a clock signal to a controller section 5. The controller section 5 detects specific marks for synchronous detection included in the data in order to synchronize a series of the data received from a read channel section 4 and demodulates the data exclusive of the specific marks for synchronous detection. A mark detecting section 11 in the controller section 5 detects the specific marks for synchronous detection from the data in the parallel state received by a shift register 10.
