This patent specification describes a novel optical information recording method for recording mark and space information. The method for recording optical information comprises the steps of generating a peak level current waveform having a high level, generating a bias level current waveform having a low level generating a normal boost level current waveform and a low boost level current waveform, driving a laser light source with the normal boost level current waveform superimposed on the low level current waveform in a normal boost level light emission and switching a drive current waveform for the laser light source to the low boost level current waveform superimposed on the low level current waveform in a peak level sampling operation.
