摘要：
A recording method of an optical recording medium comprises irradiating the medium with a laser having m pulse sets each comprising a heating pulse and a cooling pulse, in which m is a natural number; and scanning the medium with the laser at a scanning speed v to record marks each of a length nT, in which n is a natural number of 3 or more and T is a clock cycle, wherein a length TCPn of a final cooling pulse is determined in accordance with the scanning speed v using the following functions, in v
