摘要： For optical disk apparatus compatible with multiple standards, employing multiple source beams with different wavelengths, less costly implementations of the photodetecting optics section and associated circuitry are presented. A photodetector plane dedicated to RF signal detection is provided. By bandwidth combining an RF signal detected by this plane is with another signal from other photodetector planes, S/N ratio is improved. For beam splitting, diffraction gratings are used and adjustment precision requirement is relaxed greatly. AC amplifiers can be used as RF photocurrent amplifiers.

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.
