An object is to provide a recording and reproducing method of a dyestuff-based, write-once DVD medium which can obtain a good recording waveform at a time of carrying out high linear speed recording. To this end, there are provided a recording and reproducing method and a recording and reproducing apparatus of a dyestuff-based, write-once DVD medium in which each mark other than a shortest length mark is recorded on a recording layer at an optical recording medium formed by having at least a recording layer containing an organic dyestuff on a substrate having a guide groove at which a high-frequency wobble is provided, by using one pulse light at which two places which are a leading portion and a trailing end portion of a heating pulse are made to be high-output for a given time and at which a pulse light power of the leading portion of the heating pulse is greater than a pulse light power of the trailing end portion, and the recording is reproduced by reproducing light.
