| 摘要 |
An apparatus and method to accurately discriminate an optical disc type in an optical disc system which records and/or reproduces data to and/or from high density optical discs and low density optical discs includes irradiating a laser beam onto a given one of the optical discs, measuring a track error signal generated from light reflected by the given optical disc, comparing a level of the track error signal with a predetermined reference value, and discriminating a type of the given optical disc according to a comparison result.
