Abstract
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.
