Abstract

본 발명은 광디스크 플레이어의 트랙킹에러 발란스 조정장치에 관한 것으로, 종래에는 현재 광디스크 플레이어 시스템에 공통으로 적용되고 있으나 이 과정이 세트조립시 공정의 하나로 구성되어야 한다. 즉 트랙킹을 오프시키는 지그(Jig)를 이용하여 트랙킹을 오프를 한 후 계측기로 파형을 보면서 가변저항을 돌리는 작업이 필요함에 따라 사용자에게 많은 번거로움을 주는 문제점이 있었다.The present invention relates to a tracking error balance adjusting apparatus for an optical disc player. In the related art, the present invention is commonly applied to an optical disc player system. In other words, after turning off the tracking by using the jig for turning off the tracking, the user needs to turn the variable resistor while watching the waveform with a measuring instrument.

따라서 종래의 문제점을 해결하기 위하여 본 발명은 광디스크 플레이어의 트랙킹에러 발란스를 마이크로 컴퓨터와 가산기를 이용하여 자동으로 조절하도록 하므로써 세트조립시의 공정을 줄일 수 있도록 하여 사용자의 불편을 해소시키도록 한다.Therefore, in order to solve the conventional problems, the present invention allows the tracking error balance of the optical disc player to be automatically adjusted using a microcomputer and an adder so as to reduce the process during assembly of the set, thereby eliminating user inconvenience.
