| 英文摘要 | An optical information recording and/or reproducing apparatus comprises a first semiconductor laser for generating a light beam for recording or erasing information with an optical information recording medium, a second semiconductor laser for generating a light beam for reproducing recording information with the optical information recording medium, a first direct current supplying circuit for supplying a first direct current to the first semiconductor laser, a second direct current supplying circuit for supplying a second direct current to the second semiconductor laser, and a high-frequency current supplying circuit for supplying high-frequency currents to the first semiconductor laser and the second semiconductor laser, wherein the high-frequency current supplying circuit supplies a smaller high-frequency current to the first semiconductor laser than that to the second semiconductor laser. |
