Abstract
본 발명는 광픽업장치의 포커싱/트랙킹 조정장치에 관한 것으로, 정보기록매체에 기록된 정보를 광학적으로 독취하기 위한 수광소자(10)를 포함하는 광픽업장치(10A)에서 상기 수광소자(10)의 수광영역에서 얻어지는 포커싱/트랙킹에러를 자동으로 조정하기 위한 에러보상데이터를 생성하는 포커싱/트랙킹조정부(30)와, 그 포커싱/트랙킹 조정부(30)에서 생성된 에러보상데이터를 기초로 광픽업구동계(50)에 대한 에러보상전압을 생성하는 포커싱/트랙킹에러보상부(40)를 구비하여 구성되고, 포커싱/트랙킹조정부(30)는 상기 수광소자(10)의 수광영역에서 검출된 현재의 포커싱/트랙킹에러신호와 그 현재의 포커싱/트랙킹에러신호에서DC레벨제거소자(34)에 의해 DC레벨이 제거된 포커싱/트랙킹에러신호의 차이를 디지탈변환출력하는 데이터변환부(36)와, 그포커싱/트랙킹에러의 디지탈변환데이터에 의해 지정 가능한 포커싱/트랙킹에러보상 데이터가 테이블화되어 저장된 포커싱/트랙킹에러보상테이블(38)로 구성되어, 광픽업장치(10A)의 포커싱/트랙킹 조정작업이 자동으로 실행되도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for adjusting focusing / tracking of an optical pickup apparatus, wherein the optical pickup apparatus (10A) includes a light receiving element (10) for optically reading information recorded on an information recording medium. Focusing / tracking adjustment unit 30 for generating error compensation data for automatically adjusting the focusing / tracking error obtained in the light-receiving area, and based on the error compensation data generated in the focusing / tracking adjustment unit 30, And a focusing / tracking error compensator 40 for generating an error compensating voltage for 50, wherein the focusing / tracking adjusting part 30 is the current focusing / tracking detected in the light receiving region of the light receiving element 10. A data converter 36 for digitally converting the difference between the error signal and the current focusing / tracking error signal and the focusing / tracking error signal from which the DC level is removed by the DC level removing element 34; The focusing / tracking error compensation table 38 stores and stores the focusing / tracking error compensation data that can be specified by the digital conversion data of the syncing / tracking error, and the focusing / tracking adjustment operation of the optical pickup device 10A is automatically performed. Is to be run.
