摘要： PROBLEM TO BE SOLVED: To solve such the problem of conventional recording methods of optical disk using mutlipulses that the elevation of recording rate and the execution of power control are difficult and the number of recording compensating parameters are required. SOLUTION: A recording pulse of single pulse is used in the recording of the shortest mark 108 and a two-stage pulse composed of the first half and the second half is used in the recording of a long mark 125. Front edge positions 115, 118 of the recording pulse are determined by the relation between a length of immediately preceding space and a length of self-mark, in such a manner that the front edge position in a reproduced waveform of every mark length is optimized. On the assumption that the rear edge position of the recording pulse of every mark length is fixed as the position, where a specified relative positional relation with the edge of the recording clock is satisfied, power 122 of the recording pulse 101 of the shortest mark is determined, in such a manner that rear edge position 112 of reproduced waveform of the shortest mark is optimized and power 124 of the second half pulse 104 is determined at every mark length, in such a manner that the rear edge position 123 of reproduced waveform of the long mark is optimized.

摘要： PROBLEM TO BE SOLVED: To ensure stable recording of pits of small widths with a recording method for a master optical disk formed with parts exposed with recording laser beams as pits. SOLUTION: At least the two laser beams are circumferentially offset at approximately a half track in the difference of a distance from the center of rotation of the disk in such a manner that the beams do not overlap in irradiated parts. The disk is irradiated the first laser beam subjected to intensity modulation according to recording information in precedence in a recording direction, by which intermittently exposed parts (marks) are formed. The disk is irradiated with the second laser beam of the specified intensity in succession to the first laser beam, by which the disk is exposed continuously in superposition on the edges of the marks described above. The unexposed parts of the master disk are molded as the information pits on the optical disk substrate surface.

摘要： PROBLEM TO BE SOLVED: To resolve a condition in which fluctuation in the edge position of reproduced data becomes large and reproducing compatibility is not realizable while reproducing the data employing a device that is not the device used for a data recording. SOLUTION: The device is provided with reproducing learning means 13 and 24 which switch the frequency characteristic of a reproducing system that detects the change in a local optical constant, to a prescribed frequency characteristic. The device is also provided with a recording learning means 20 which records a test pattern on an optical information recording medium, reproduces the pattern and compensates the starting or the stopping edge mark of a recording pulse for every combination of a mark interval and the length of the space that lead or follows, so that the edge position of binarized reproduced data becomes a desired position. Since the frequency characteristic of the reproducing system is arranged to be constant before learning the amount of an edge shift caused by thermal interference between marks, the lengths of recorded marks and spaces are made constant at all times and the reproducing compatibility among the devices is improved.
