APPARATUS AND METHOD FOR CONTROLLING WOBBLE PHASE LOCK LOOP

摘要

PURPOSE: A wobble phase locked loop control device and a method thereof are provided to record data at double speed by turning on or off a data phase locked loop and a wobble phase locked loop. CONSTITUTION: A wobble phase locked loop(100) synchronizes a wobble of an optical disk with a phase. A control unit(300) selectively turns on or off the wobble phase locked loop and a data phase locked loop(200). The control unit temporarily suspends data writing operation. The control unit turns on the data phase locked loop and turns off the wobble phase locked loop. The data phase locked loop synchronizes the data of the optical disk with the phase.
