摘要： PROBLEM TO BE SOLVED: To provide an optical recording/reproducing method and device for obtaining a preferable recording waveform when performing a high linear velocity recording to a pigment-based write once type DVD medium. SOLUTION: The pigment-based write once type DVD medium recording/reproducing method is implemented as follows. The shortest mark is recorded with a higher output pulse than the other marks onto a recording layer mainly composed of organic pigment and formed on a substrate having a wobbled guide groove. The third shortest mark and after are recorded by a single pulse light having a pulse power equal to that of the second shortest mark which has been outputted highly when the pulse rear end has been outputted highly for a predetermined period of time. When performing mark recording, a cooling pulse is irradiated to the rear end and after of the pulse of all the marks and the irradiation light intensity is maintained at 0.1 mW or below for a predetermined period of time.

摘要： PURPOSE:To obtian a high-S/N moire free optical disk by forming even pits by coating the recordng layer of the optical disk with a shaped hard film, which never fuses when holes are made in the recording layer, within a specific thickness range. CONSTITUTION:On a transparent substrate 1 of glass, plastic, etc., a recording layer 2 of metal, such as Te, or organic coloring matter is formed and on the layer 2, a shaped film 3 having tens - thousands Angstrom thickness is formed by using SiO, SiO2, ZnO, thermosetting resin, etc. In a thus obtained optical disk, pits 4 in the layer 2 are formed with a laser beam, and consequently irradiated parts of the layer 2 fuse to form projection parts 5 having swelling circumferences by surface tension, so that the film has swelling parts 6. The hard film 3, however, suppresses the formation of those projection parts 5, so the size of each pit 4 is made uniform.
