摘要： In a recording system in which linear velocity during the write operation changes, it is difficult to obtain write strategy parameters in every linear velocity with trial writing. The optimum write strategy condition under the high speed or low speed operation is obtained with trial writing or the like and a value of power compensation is obtained from the frequency characteristic stored in the table. Fluctuation in performance of optical disk drive, deterioration by aging, and temperature characteristic can be compensated.

摘要： Information recording equipment of the present invention includes a multiplexer to generate n pieces of synchronous high-speed pulses. Instead of a normal m:1 multiplexer configuration for parallel-serial conversion, an m:n multiplexer configuration is used which generates m pieces of output signals from n pieces of input signals. The recording equipment including the m:n multiplexer enables high-resolution and high-speed pulse generation and carries out multipulse and multilevel signal generation.

摘要： In order that it is realized to put 16× speed DVD-RAM in practice, a recording method coping with CAV (constant angular velocity) and a method for improving S/N ratio are provided and an optical disk device using them is provided. In order that a cutoff phenomenon of pulse in a laser driving circuit may not occur, the shortest pulse width is set at 1 Tw or more where Tw indicates a window width, and a recording pulse in which a 4T mark is recorded with a mono pulse where T indicates a detection window width and the parameter setting range are prescribed. Simultaneously, a reproduction power for 6× speed or more is set at 1.5-2.0 mW, different from a conventional value, and a setup sequence with which deterioration of data in reproducing does not occur is provided. Thereby it becomes possible to put 16× speed DVD-RAM in practice.

摘要： An objective of the present invention is to enhance reliability of recorded data by preventing deterioration of OPC (Optimum Power Calibration) accuracy due to an influence of inter-layer interference in an optical disk device capable of writing in a multilayer optical disk. Aiming at the objective, a relationship between asymmetry and a signal modulation depth, which are measured by use of a standard driver is referred, and thereby an offset caused by a device, a disk, a writing state of another layer and the like is compensated. Thus, OPC is executed.

摘要： The present invention achieves an optical recording and reproducing apparatus focusing two opposed beams of light at a same place in an optical recording medium to record a standing wave generated by interference of the two beams of light. In the apparatus, phase information is recorded in the optical recording medium by a phase modulating means for modulating phase of one of the two beams of light. The reproduction reference light generated from a light source is allowed to interfere with reproduced light generated by projecting one of the two beams of light onto the optical recording medium to generate three or more beams of interfering light having different interference phases are simultaneously generated. The three or more beams of interfering light are then detected, and the phase modulated by the phase modulating means is demodulated from an output of the detector.
