Abstract

PURPOSE:To attain recording/reproduction/erasure with high reliability by writing a data representing the recording/erasure/reproducing temperature characteristic to a part of a control track and reading the data so as to decide an optical beam power. CONSTITUTION:A control section 41 reads a recording environment characteristic of an optical recording medium and a medium ambient temperature data from a control track via an optical head 42. The control section 42 controls a laser power control 43 in response to the read data to radiate a laser beam with a proper power onto the recording medium.
