| 英文摘要 | An optical pickup for reading information written on an optical disk is equipped with a vertical multi-mode converted laser diode which emits light, means for focusing the emitted light from the laser diode onto the optical disk, and means for receiving reflected light from the optical disk in order to read the information written on the optical disk, wherein the coherent distance of the emitted light from the laser diode is made shorter than the optical path length of the optical pickup. |
