    摘要： A recording quality is improved when performing information recording or rewriting on a phase-change type optical recording medium according to a multi-speed method. A recording apparatus (1) performs optical informational recording or rewriting on a phase-change type optical recording medium (2) according to the multi-speed method by a recording wave which has been subjected to a pulse-width modulation (PWM). Recording or rewriting of a 1-signal having a signal with nT after modulation is nT is performed by a pulse train recording wave having a pulse part fp, a multipulse part mp and a pulse part ep. On the assumption that a time with of the pulse part fp is x and a time width of the pulse part ep is z, a relationship between the time width x and the time width z satisfies 3z≦x≦4.5z.

    摘要： To provide a method for rewriting data in a three-dimensional optical memory element created in glass with ultrashort light pulses capable of moving created bits for rewriting.
    A method for rewriting data in a three-dimensional optical memory element created in glass (18) with ultrashort light pulses comprises the steps of: creating a bit (23) due to a photo-induced contrast in index of refraction inside the glass (18) in three dimensions depending of the strength of a first ultrashort-pulse laser beam; and irradiating the bit (23) created in three dimensions with a second ultrashort-pulse laser beam having a lower energy than the strength of the first ultrashort-pulse laser beam, and when condensing the laser beam with an optical lens (17), condensing the laser beam at a point shifted from the bit (23) to be moved by a predetermined distance in the opposite direction from the direction of propagation of the laser beam, thereby moving the bit (23) for rewriting.

    摘要： Such a trouble occurs in the conventional optical information recording method that the tailing end sections of marks become larger and reproduction jitter becomes worse after overwriting due to the quick cooling of the tailing ends of the marks and signal deterioration occurs due to a thermal damage resulting from an increase in the number of cycles. Therefore, a mark tailing end correcting pulse train is added to a recording pulse train and the projection of laser light with bias power is performed between the recording pulse train and projection of laser light with cooling power or between the recording pulse train and mark tailing end correcting pulse train. In addition, the starting time of the projection of laser light with cooling power, the width of area irradiated with cooling power, and shape of the mark tailing end correcting pulse train are changed in accordance with the length of the mark. When the recording pulse train is composed of a leading edge pulse, terminating pulse, and pulses between the leading edge and terminating pulses, the projection of laser light is performed with cooling power and the projection of laser light with bias power is performed between the recording pulse train and cooling power. In addition, when the recording pulse train changes in accordance with the lengths of marks and interval between marks, the starting timing of the projection of laser light with cooling power is decided based on the delaying amount of the terninating pulse or a clock.
