RECORDING POWER CONTROL METHOD FOR OPTICAL DISK DEVICE

RECORDING POWER CONTROL METHOD FOR OPTICAL DISK DEVICE

PROBLEM TO BE SOLVED: To stabilize recording quality independently of temperature change. SOLUTION: The phase error amount of a recording signal is measured (S1), and then recording power is controlled based on the phase error amount (S2, S3) obtained by measurement. COPYRIGHT: (C)2009,JPO&INPIT
