Abstract (en)
[origin: EP0751506A2] A writable optical disc has an information writing track (2), and a guiding track (3) for introducing a laser beam to the information writing track (2). The guiding track (3) has prepit information recorded thereon, the prepit information including at least address information of the optical disc (1). The prepit information (4) is recorded on the guiding track (3) at a position where interference of adjacent guiding tracks (3) with the prepit information is prevented. The information writing track (2) is a groove track, and the guiding track (3) is a land track. <IMAGE>
