An optical information recording device includes a linear velocity setting circuit for setting a first linear velocity v 1 and a second linear velocity v 2 higher than the first linear velocity v 1 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 Pbt 1<= Pe 1 and Pe 2< Pbt 2<= Pwa 2 , where Pbt 1 represents a first inter-pulse power level indicating a power level between recording pulses for the first linear velocity v 1 , Pbt 2 represents a second inter-pulse power level indicating a power level between the recording pulses for the second linear velocity v 2 , Pwa 2 represents a recording power level indicating a power level of the recording power for the second linear velocity v 2 , Pe 1 represents a first erase power level indicating a power level of the erase power for the first linear velocity v 1 , and Pe 2 represents a second erase power level indicating a power level of the erase power for the second linear velocity v 2.
