OPTICAL PICKUP DEVICE INTERRUPTING OPTICAL NOISE AND OPTICAL RECORDING/PLAYING DEVICE ADOPTING THE SAME

摘要

PURPOSE: An optical pickup device interrupting an optical noise and an optical recording/playing device adopting the same are provided to interrupt the optical noise completely and simply by placing a monitoring optical pickup to a position that the light reflected from a signal detecting optical pickup is not advanced. CONSTITUTION: A grating(13) splits the light emitted from a light source(10). A reflector partially reflects the light emitted from the light source by installing around the grating. The monitoring optical detector(11) is installed on an advancing path of the light reflected from the reflector. A light path converter(17) converts the advancing path of the light passing the grating. An objective lens(23) collects the light reflected by the light path converter to a disc(25). The signal detecting optical disc detector(30) detects a focus servo signal and a tracking servo signal by receiving the light reflected from the disc.
