Patent

CA 2310947

The present invention relates to an optical disc apparatus, an optical disc reproducing method and an optical disc. Thereby, for example, the present invention can be applied an optical disc system in which the desired data can be recorded through meander of the groove in view of surely reproducing the data recorded in higher recording density. The data recorded through the meander at wall surface of groove can be reproduced from change of the polarizing plane of the returning beam obtained through radiation of the laser beam.
