Patent ID: 7505380

Claim:
An apparatus for preventing a writing error from occurring on an optical disc in an optical disc drive having a wobble signal generator, the apparatus comprising: an interpolation ATIP sync signal detector which receives a wobble signal from the wobble signal generator of the optical disc drive and detects an interpolation ATIP sync signal from the wobble signal, the interpolation ATIP sync signal being an ATIP sync signal which is artificially interpolated by the wobble signal generator when the wobble signal generator does not normally generate an ATIP sync signal; a number determiner which determines a number of interpolation ATIP sync signals and generates a writing speed transformation control signal based on the number of interpolation ATIP sync signals determined; and a writing speed adjuster which receives the writing speed transformation control signal from the number determiner and adjusts a writing speed of the optical disc drive to a speed of the optical disc on which writing is to be performed.
