Optical information recording/reproducing apparatus supplying a smaller high-frequency current to a first semiconductor laser for generating a light beam to record information than to a second semiconductor laser for reproducing recorded information

摘要

An optical information recording and/or reproducing apparatus includes a first semiconductor laser for generating a light beam for recording or erasing information on an optical information recording medium. Also provided is a second semiconductor laser for generating a light beam for reproducing recording information from the optical information recording medium, and a first direct current supplying circuit for supplying a first direct current to the first semiconductor laser. A second direct current supplying circuit supplies a second direct current to the second semiconductor laser, and a high-frequency current supplying circuit supplies high-frequency currents to the first semiconductor laser and the second semiconductor laser. The high- frequency current supplying circuit supplies a smaller high-frequency current to the first semiconductor laser than to the second semiconductor laser.
