Abstract
In a recording strategy suitable for high-speed recording, a laser driving signal includes a top pulse having a pulse width corresponding to a recording mark length and multi-pulses having a period 3-times larger than a base clock period of a recording mark. The top pulse is has the first identical-shape top pulses when the recording mark length is 3nT ('n' is a natural number), the second identical-shape top pulses when the recording mark length is (3n+1)T, and the third identical-shape top pulses when the recording mark length is (3n+2)T.
