Abstract
An optical pickup for emitting a laser beam is provided for reading data recorded on an optical disc. The axis of the laser beam is tilted at a skew angle from a perpendicular line to the surface of the disc. Error rate in reproduced data read out by the pickup is determined, and an inferior disc having a rare error rate is eliminated.
