OPTICAL PICK-UP APPARATUS FOR A DIGITAL VIDEO DISK PALYER AND A COMPACT DISK PLAYER

摘要

Disclosed are an optical pickup apparatus for both a digital video disc player (DVDP) and a compact disc player (CDP).;The disclosed device is arranged on an optical axis between a light source for generating and outputting laser light, an objective lens for converging light incident from the light source to form an optical spot on the optical disk, and changing an optical path between the light source and the objective lens. An optical path converting means and a photodetector for receiving information reflected from the optical disk to detect information and error signals, wherein the photodetectors are arranged adjacent to each other and receive light independently from each other; D The first photodetection unit consisting of four partition plates and E, F, G disposed adjacent to each other on the periphery of the four partition plates A, B, C, and D of the first photodetector so as to receive light independently. , H is characterized in that the second light detection section consisting of four partition plates.
