摘要： Before original information is recorded in areas such as a recording medium management area where the same pattern of information is recorded many times, a dummy pattern that minimizes a recording film flow is recorded. Because the direction of the recording film flow depends on the length of a mark length, the dummy pattern is a pattern including marks with a unique length. Randomly or sequentially selecting and recording a plurality of dummy patterns, each with a recording film flow direction different from others, prevents jitters, which will be caused by the recording film flow, from increasing.

摘要： According to this invention, since the range of power necessary for erasing an overwritable magneto-optical recording medium is set to 2.5 mW or above, overwriting is possible without erase residue due to mark (magnetic domain) diameter difference, tracking offset, ambient temperature variation and characteristic dispersion between magneto-optical recording media and thus the magneto-optical recording medium has high reliability. Moreover, the rate of change, K of the switching field of the memory layer relative to temperature at around an erase start temperature can be controlled to be a constant value so that an erase power margin can be increased and that the tolerance to the reading light when the ambient temperature rises can be improved.

摘要： An information recording method using an optical recording medium includes the steps of forming a plurality of recording pulses to irradiate the optical recording medium and recording information to the optical recording medium by irradiating the recording pulses on the optical recording medium. At least a leading edge of a first recording pulse and a trailing edge of a last recording pulse of the recording pulses shift at a shifting value, wherein the shifting value is determined by combinations of a length of M(n) of a mark being currently written and at least one of a length s(n−1) of a space precedent to the mark and a length s(n+1) of a space subsequent to the mark.
