ABSTRACT:
An optical disc discriminating system comprises: a tracking error signal generating means adapted to generate a tracking error signal whose amplitude level varies with a groove depth of information tracks on an optical disc; a tracking servo means for directing a laser beam along an information track on the optical disc in accordance with the tracking error signal; a comparator adapted to compare the amplitude level of the tracking error signal supplied from the tracking error signal generating means with a reference level, with a tracking servo loop of the tracking servo means in an opened condition; a discriminating means adapted to discriminate the first and second groups of optical discs in accordance with a result from the comparator.
