<P>PROBLEM TO BE SOLVED: To provide a recording method capable of enlarging a power margin to reduction or temporary fluctuations of laser power when recording information in a recording layer and a recorder using the recording method. <P>SOLUTION: In the method by which recording marks are formed in the recording layer, a pulse train having combination of a first level, a second level which is larger than the first level and a third level which is larger than the second level is generated according to the length nT (n is an integer and T is a reference timing period) and in the recorder, a laser beam is generated according to the pulse train. Moreover, in the recorder, the recording layer is rotated at a linear velocity having magnifications (m) to a defined linear velocity and in a recording mark whose length is nT in which (n÷m) becomes 5 or more, at least first two pulses having the third levels in a pulse train are generated so as to have first pulse width wider than the pulse width of other pulses having the third levels which follow these two pulses. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
