摘要： PROBLEM TO BE SOLVED: To enable allotting independent information for discrimination in all recording areas when one information for discrimination is used for both two tracks in common. SOLUTION: Discrimination for information (2) is arranged so that positions in the direction along an information track are different between adjacent tracks each other and they coincide between a track and a next track but two, also, it is arranged at intermediate part of two tracks, and tracks of a groove part (3) and groove interval part (4) are coupled. Further, the same does not appear in the groove part and the groove interval part. Thereby, information for discrimination is doubled and reliability is improved. Also, by arranging the groove part and the groove interval part so as to connect each other, as continuous access to a groove interval part recording track from a groove part recording track can be performed, effective transfer speed of information is improved, recording and reproducing of continuous information such as animation information and the like is easily performed.

摘要： PURPOSE:To make user data possible to be recorded with always optimum write laser strength regardless of the change in the temperature of a recording medium by test writing at an optional time interval regardless of a write instruction from a host device in an optical or a magneto-optical recorder. CONSTITUTION:The test data are test-written on a test write area 42 provided on several positions of the surface of a disk medium 4 with various laser strengths, and an optimum write laser driving current value (laser strength) is set previously based on the regenerative signal, and the user data are recorded by the current value. The initial test write is performed at the time of loading the medium on a device, and the test writes after second times are decided so that the longer the time interval until the test write of next time, the smaller the difference of the laser driving current setting values based on the test writes of the last time and this time. Thus, the test write time interval becomes shorter when the change in the temperature at the time of loading the medium is large, and the time interval becomes longer when the change in the temperature is smaller, and the number of times of the test write is reduced.

摘要： PROBLEM TO BE SOLVED: To reduce the time required for preparing the recording/reproducing operation at the time when the power is supplied and when a disk is inserted, by reading out the medium control information of the inner peripheral side first against the re-writable disk and sampling the data for adjusting the recording power from a drive test zone, and next, sampling the data from the drive test zone of the outer peripheral side and reading out the medium control information. SOLUTION: By a microprocessor 4, the medium control information of the inner peripheral side of the disk 13 is read in by an optical head circuit 10 and stored in a buffer memory 3. Next, test patterns are written in and read out against the drive test zones of the inner and outer peripheral sides, then the result is stored in a control memory 5, and by using this result, the optimum recording power is calculated and set to a recording circuit 8. Next, the medium control information of the outer peripheral side is read in and stored in the buffer memory 3, then from this information and the medium control information of the inner peripheral side, the required information is stored in the control memory 5. Thus, the futile movement of the optical head circuit 10 is eliminated, and the efficient starting process is attained.

摘要： PROBLEM TO BE SOLVED: To allocate discrimination information independent of respective recording areas while sharing one discrimination information with two tracks. SOLUTION: Respective tracks 3, 4 divided at every recording unit arranged radially in the radial direction, and the discrimination information 21, 22 showing the recording unit are arranged at every recording unit, and the discrimination information are arranged in an intermediate part of tracks adjacent to each other, and the positions of the discrimination information in the direction along the information track are arranged so as to be different from each adjacent track and to be matched with the next track of adjacent track. Thus, the discrimination information is arranged at every recording unit, and cross talk is eliminated.
