摘要:
An optical information recording device includes a linear velocity setting circuit for setting a first linear velocity v1 and a second linear velocity v2 higher than the first linear velocity v1 for a optical information recording medium, a recording pulse generation circuit for generating a recording pulse signal, depending on the setting by the linear velocity setting circuit, and a laser drive circuit for irradiating the medium with the laser light based on the recording pulse signal generated by the recording pulse generation circuit. The laser drive circuit controls a power level of the laser light so that Pbt1≦Pe1 and Pe2
