摘要：
A random seed scramble for preventing the deterioration of a medium is applied to the next generation optical disk. A seed is stored to a BIS area. ID or an EDC is checked to hold interchangeability before and after scramble release. When no error is generated in data before the scramble release, it is recognized as an unscrambled disk. In contrast to this, when no error is generated in data after the scramble release, it is recognized as a scrambled disk. An information storing area showing an area to be rewritten by performing the scramble and an area to be rewritten without performing the scramble is arranged.
