Patent ID: 7715293

Claim:
A method of recording to an optical recording medium comprising: recording a mark of time length nT (where n is a natural number of 3 or more, and T represents a clock cycle) in an optical recording medium which can support different recording speeds and has a constant information line density, and irradiating the optical recording medium, the optical recording medium being irradiated with light of alternating m 1 heating pulses of power Pw and m 1 cooling pulses of power Pc (where m 1 is a natural number smaller than n) provided v<v 0 (where v is a scanning speed and v 0 is a scanning speed which is unique to each optical recording medium), the optical recording medium being irradiated with light of alternating m 2 heating pulses of power Pw and m 2 cooling pulses of power Pc (where m 2 is a natural number smaller than n) provided v≧v 0 , wherein an average of n/m 1 values and an average of n/m 2 values satisfy the condition that the average of n/m 1 values>the average of n/m 2 values.
