摘要：
A recordable optical disc (20) on which information is recorded by applying a light beam on the surface thereof, includes: a first recording area on which information is recorded and reproduced while the disc is rotated at a first linear velocity; and a second recording area on which information is recorded and reproduced while the disc is rotated at a second linear velocity. The first recording area and the second recording area include guide grooves having wobble frequency lower than frequency band of EFM signal.
