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： In an apparatus for recording data on a rewritable optical disk with a mark edge recording the occurrence of edge shift is compensated for. As a first power of a laser beam is greater than a second power, start and termination ends of each mark are produced by irradiation of the first power and a remaining intermediate portion of the mark is produced by irradiating the first and second powers alternately at equal intervals of a predetermined duration which is shorter than a period of a clock pulse. Also, the start and termination ends of the mark are specifically dislocated corresponding to a length of the mark and lengths of two neighbor spaces before and after the mark.

摘要： An analog-to-digital converter executes analog-to-digital conversion of a first analog video signal at a predetermined sampling frequency "fs". A time base converter converts a time base of an output signal from the analog-to-digital converter at a predetermined time base conversion frequency "ftci". A digital output signal from the time base converter is converted into a corresponding second analog video signal in response to a clock signal of a frequency corresponding to the frequency "ftci". The second analog video signal is converted into an FM video signal recorded on a video region of an optical disk. A binary audio digital signal is converted into a multi-level form digital audio signal. The binary audio digital signal has a data rate corresponding to the frequency "ftci". The multi-level form digital audio signal has a data rate "ftci/n" and 2.sup.n discrete amplitude levels where "n" denotes a predetermined integer. The multi-level form digital audio signal is converted into a corresponding analog audio signal in response to the clock signal of the frequency corresponding to the frequency "ftci". The analog audio signal is converted into an FM audio signal recorded on an audio region of the optical disk. A data signal generator generates a digital data signal at a data rate "ftci/m" where "m" denotes a predetermined integer. The digital data signal is converted into a corresponding analog data signal in response to the clock signal of the frequency corresponding to the frequency "ftci". The analog data signal is converted into an FM data signal recorded on a data region of the optical disk.
