摘要： A recording medium having a dummy signal area on at least one side of a recording area is used and information is recorded with a dummy signal added to at least one of the leading and trailing sides in the recorded information signal. The user data area remains unaffected by repeated overwriting so that recorded user data is reproduced correctly. In particular, the wave form distortion caused by fluidization of a recording film remains at the dummy signal area and does not affect the user data area, so that the reproduction of the target information (user data) is assured.

摘要： An optical recording medium includes grooves and lands on a substrate in which prepits are disposed on an extension of the boundary between a groove and a land such that they are located uniformly on both sides of the center line of the groove or the land and that they do not exist on the both sides of any specific position of the center line of the groove or the land. Through this, at least synchronous information would be obtained with ease and tracking offset would be decreased.
