OPTICAL INFORMATION RECORDING METHOD AND OPTICAL INFORMATION RECORDING DEVICE

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 senerating 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 < Pbt2 ≤ Pwa2, where Pbt1 represents a first inter-pulse power level indicating a power level between recording pulses for the first linear velocity v1, Pbt2 represents a second inter-pulse power level indicating a power level between the recording pulses for the second linear velocity v2, Pwa2 represents a recording power level indicating a power level of the recording power for the second linear velocity v2, Pe1 represents a first erase power level indicating a power level of the erase power for the first linear velocity v1, and Pe2 represents a second erase power level indicating a power level of the erase power for the second linear velocity v2. <IMAGE>
