摘要： In an optical information recording medium having at least two information layers, guide grooves for tracking or sample pits or information pits corresponding to information signals are formed on a surface of a first substrate (1). A first information layer (2) formed by a thin film for reflecting a portion of a light beam (7) made incident on the first substrate (1) and permitting penetration of a portion of the light beam (7) is formed on a surface of the first substrate (1). Guide grooves for tracking or information pits corresponding to information signals are formed on a surface of a second substrate (3). A second information layer (4) having a reflectance higher than that of the first information layer (2) is formed on a surface of the second substrate (3). Between the first information layer (2) and the second information layer (4), there is formed a transparent separation layer (5) for positioning the first information layer (2) and the second information layer (4) to be spaced a predetermined distance apart from each other.

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.
