The object of the present invention is to provide an optical recording and reproducing method for a dye-based recordable optical recording medium includes recording shortest marks on an organic dye recording layer formed on a substrate having a guide groove with a wobble formed thereon using one pulse which is more highly energized than pulses of each of marks other than the shortest marks; recording each of the third shortest marks and still longer marks using one pulse beam of which the rear edge is energized for a given length of time, and the energized pulse power is equal to the pulse power of each of the second shortest marks, and irradiating cooling pulses onto the backwards of the respective pulse beams of all the marks during recording at an optical energy of 0.1 mW or less for a given length of time, and provide an apparatus for the same.
