| 摘要 |
An optical recording method for an optical recording medium having a recording layer containing an organic colorant on a transparent substrate, which comprises applying a recording laser beam divided into n-2 (wherein n is an integer of at least 2) pulses (or into 1 pulse when n is 2), to the optical recording medium, to form a mark having a recording data of nT (wherein T is the reference clock period), wherein the length of the forefront pulse is at least 1.7T and at most 2.4T, and the lengths of the second and subsequent pulses (multi-pulses) are at least 0.7T and less than 1.0T.
