RECORDING MEDIUM, ADDRESS RECORDING METHOD AD DEVICE THEREFOR, AND RECORDING AND REPRODUCING DEVICE AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a recording medium with a narrowed track pitch. SOLUTION: In a groove or a land as a track where data are recorded or reproduced, right and left edges 12-1 to 12-5 in every other track are wobbled in accordance with address information. Consequently, a prescribed wobbled edge is separated from a wobbled edge of the other track by one track pitch or more, and when the address information is read out of these edges, interference from an edge of the other track can be suppressed.
