Abstract
A disc having recordable and recorded areas discretely scattered over it at the same time is formed with a guard band to prevent the recorded area from being destroyed by a track jump caused by an undue impact or vibration applied to the disc during a recording operation. Additionally, storing in memory information of an edge of a recorded area by a predetermined amount before recording, the edge providing a boundary between the recorded area and a recordable area, allows recovery of data in the recorded area destroyed by a track jump caused by an undue impact or vibration applied to a disc.
