OPTIMUM POWER CALIBRATION APPARATUS AND METHOD FOR REWRITABLE OPTICAL DISC

摘要

PURPOSE: An optimum power calculation device and a method are provided to perform optimum operation to a blank disc and a used disc by performing optimum power calculation operation by discriminating a disc. CONSTITUTION: A control unit(17) performs data recording and play operation to an optical disc(10). The control unit performs optimum power calculation operation before performing data recording and play operation. The control unit controls an optical pickup(11), a motor driving unit(14) and a recording/play unit(15) and accesses a disc identification zone. The control unit applies a previous optimum power calculation result and light strategy information and records. The control unit lifts an optimum power calculation mode and performs data recording operation.
