A recording method comprising the steps of modulating data to be recorded to generate a plurality of recording modulation codes, and emitting a pulsed light beam to a data storage medium, so that a plurality of recording marks and spaces are recorded on the data storage medium, the lengths of the recording marks and spaces being defined by the modulated data, wherein at least two of the plurality of the recording marks comprise: a first pulse which is disposed at a front and forms a leading edge of the recording mark; a last pulse which is disposed at a backend and forms a trailing edge of the recording mark; and multi-pulse train (507,509) which is disposed between the first pulse and the last pulse and forms a center of the recording mark, the multi-pulse train (507,509) having a pulse period longer than T, T representing a reference period of the recording modulation code; the number of pulses in each of the recording marks is increased by one as the recording mark is increased in length by 2T, the plurality of recording marks have different lengths differing by T or multiples thereof from one another; and the shortest recording mark and the second shortest recording mark are constituted by a single pulse.
