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： On an optical disk medium according to the present invention, address information is recorded along a wobbling track groove 2. The track groove 2 is made up of a plurality of unit sections 22 , 23 . Each of these unit sections 22 , 23 has side faces that are displaced periodically in a disk radial direction. This displacement oscillates at a single period in a tracking direction. However, the displacement pattern differs depending on "each bit of address information (subdivided information)" allocated to each of the unit sections 22, 23.

摘要： A power control device for controlling a power of a light source of an optical beam directed to an optical medium. The power control device includes a reflected light detector for detecting reflected light from the optical medium when irradiated by an optical beam which is following a track; an arithmetic unit for calculating from the reflected light a transmissivity of light transmitted from a disk surface to a recording layer or an amount of directed light on the recording layer of the medium; and power control means for controlling the power of the light source for emission based on a calculation result produced by the arithmetic unit.

摘要： Conventionally there has been a problem that when information is recorded on an optical disk with variation of its characteristics by means of an apparatus with variation of its characteristics, proper recording is not performed and the reproduced signal contains an error. According to the invention, recording pulse standard conditions specifying the position of a recording pulse for each of combinations of mark lengths and space lengths are read from a writable optical disk. Under the recording pulse standard conditions, trial-write is carried out while varying the recording pulse standard conditions all at once or individually to find the most suitable recording pulse conditions, thereby reducing the jitter.

摘要： An optical disk includes a land and a groove. On this optical disk, data is recorded on both the land and the groove. A distance between the center of the land and the center of the groove adjacent to the land is 0.28 µm or more. The optical disk has a data efficiency of 80% or more. Thus, an optical disk having a storage capacity of 25 GB or more can be provided.
