摘要： The S/N ratio is improved for recording data to grooves (2-1,2-2) of an optical disc so that as much information as possible can be recorded at the lowest possible frequency band. An optical disc using wobble patterns to record different information has a first groove (2-1) having a first wobble pattern (22) in which one wobble period has a sharp rising edge and a gradual falling edge; and a second groove (2-2) having a second wobble pattern (24) in which one wobble period has a gradual rising edge and a sharp falling edge. Each of the first and the second wobble pattern is represented by a first fundamental and a second harmonic of a Fourier series. The polarity of the second harmonic, which is an even harmonic, of the second wobble pattern is opposite that of the first wobble pattern. A method for manufacturing this optical disc is also provided.

摘要： An optical recording medium having plural recording layers includes a first recording layer on which first data is to be recorded and a second recording layer on which second data is to be recorded, the first and second data being relevant to one another. The first and second recording layers are layered together, with the second data being recorded at a location in the second recording layer in the vicinity of a location in the first recording layer where the first data relevant to the second data is recorded. Replay signals of variable configurations can be obtained by suitably synthesizing data read out from the respective recording layers.
