摘要：
Herein disclosed is a recording apparatus for using a semiconductor laser 1 as a light source so that the scanning operation may be conducted with the laser beam which has been modulated on the basis of picture information. The drive current of the semiconductor laser 1 for making the monitor current of an optical output constant is determined before the beginning of a recording period so that the drive current may be used as that of the semiconductor laser 1 during the recording period.
