  • Apparatus and method for preventing writing error from occurring on optical disc
    Patent number: 7505380
    Abstract: An apparatus for preventing a writing error from occurring on an optical disc. The apparatus includes an interpolation ATIP sync signal detector, a number determiner, and a writing speed adjuster. The interpolation ATIP sync signal detector receives a wobble signal from the wobble signal generator of an optical disc drive to detect an interpolation ATIP sync signal from the wobble signal. The number determiner determines a number of interpolation ATIP sync signals and generates a writing speed transformation control signal based on the determination result. The writing speed adjuster receives the writing speed transformation control signal from the number determiner to adjust a writing speed of the optical disc drive.
