OPTICAL DISK DRIVE FOR WRITING A RE-WRITABLE OPTICAL DISK AND METHOD THEREOF

摘要

An optical disk drive of recording a re-writable optical disk and the method thereof. First, an optimum power is determined. A gain of a SBAD (Sub Beam Adder) signal is adjusted for generating an calibrated SBAD signal such that the calibrated SBAD signal maintains at the same level during a write power phase and a read power phase substantially. Then, the re-writable optical disk is recorded by using the optimum power. Next, a defect of the re-writable optical disk is detected according to the calibrated SBAD signal. Then, the optical disk drive will jump over the defect and prevent it from being data-recorded so as to avoid system malfunction.
