ABSTRACT:
A laser drive circuit is utilized to record data with a good signal quality over a wide range of linear velocities to an optical information recording medium. Specifically, the laser drive circuit of an optical information recording apparatus sets a ratio of a recording power to a power at which a reproduction signal quality reaches a threshold value to be relatively low at low velocities, and relatively high at high velocities.
