摘要： An apparatus and method are provided receiving wobble signals indicative of a wobble pattern formed on an optical medium. A wobble lock/unlock detector detects whether the wobble signals exist during a wobble window period and generates wobble lock/unlock signals indicative thereof. A wobble defect detector counts the wobble window signals in response to the wobble lock/unlock signals indicating that the wobble signals do not exist during the wobble window period, detects a wobble defect in response to the counted wobble window signals satisfying a defect decision condition, and outputs a defect detection signal indicative thereof.

摘要： A method protecting a header region formed in an optical disc when a signal is written on the optical disc and an apparatus therefor. The method protecting a header region of an optical disc write apparatus comprises detecting the header region from an RF signal detected from the optical disc through a pick up, generating a write clock, generating a write control signal whose state is inverted after the lapse of a predetermined clock by counting the write clock, generating a write stop signal when the write control signal is generated in the header region detected in the detecting of the header region, and controlling the intensity of the write laser beam corresponding to the write control signal. The generating of the write stop signal comprises feeding the write control signal back to the generating of the write control signal to control the write control signal.

摘要： A method of overwriting data in a linking loss area. The method includes the operations of (a) determining whether or not the first sector of a block in which it is desired for data to be recorded is a linking loss area, and if it is determined that the first sector is a linking loss area, reading the previous block; (b) modifying data type identification information of the last sector of the previous block after completing reading the previous block; and (c) recording data in blocks starting from the previous block. According to this method, based on determination of whether or not the first sector of the block in which it is desirable to record data is a linking loss area, data is recorded in the blocks starting from the current block or from the previous block so as to prevent errors in reproducing. By doing so, the method improves error correction effects.
