DATA RECORDING DEVICE OF AN OPTICAL DISK DRIVE CAPABLE OF PREVENTING LOWERING OF DATA RECORDING QUALITY DUE TO A SERVO DEVIATION AND A METHOD THEREOF

摘要

PURPOSE: A data recording device of an optical disk drive and a method thereof are provided to detect a servo deviation while performing focus and tracking servo operations, thereby variably controlling a data recording operation based on the servo difference.;CONSTITUTION: A recording/reproducing unit records or reproduces data on an optical disk. A control unit(18) controls focus and tracking servo operations of an optical pickup. The control unit detects a servo difference while focus and tracking servo operations are performed in a specific area of the optical disk. The control unit variably controls a data recording operation based on the servo difference. The control unit searches the outmost perimeter area of a preset optical disk before a data recording operation.;COPYRIGHT KIPO 2012
