ABSTRACT:
A disc, such as a magneto-optical disc or an optical disc, for recording data. The disk includes a first track and a second track. The first track is formed at a first level in the disc and is for recording data in a first format. The second track is formed at a second level in the disc and is for recording data in a second format. The first level is a different level than the second level, and the first format is a different format than the second format.
