Abstract
본 발명은 슬레드 모터축에 마킹부재를 고정설치하고서 광센서에 의해 상기 마킹부재에서 반사된 광을 기초로 슬레드 모터의 회전수를 감지하고, 슬레드 모터의 회전수에 의해 고속으로 목표트랙을 설치할 수 있도록 된 광디스크의 고속트랙서치장치를 제공하기 위한 것이다.According to the present invention, the marking member is fixed to the sled motor shaft, and the rotation speed of the sled motor is sensed based on the light reflected from the marking member by an optical sensor, and the target track is operated at a high speed by the rotation speed of the sled motor. It is to provide a high-speed track search device for an optical disk that can be installed.
이를 위해 본 발명의 광디스크의 고속 트랙서치장치는, 슬레드 모터(1)와, 상기 슬레드 모터(1)를 구동하기 위한 모터구동부(7), 상기 슬레드 모터(1)의 구동력에 의해 광픽업(17)을 이송시키는 이송메카니즘(13∼16)을 갖춘 광디스크 장치에 있어서; 상기 슬레드 모터(1)의 회전축에 고정설치된 것으로 그 한쪽면에 등간격으로 마킹된 회전부재(2)와, 발광소자(3A)와 수광소자(3B)로 구성되어 상기 회전부재(2)의 마킹을 감지하는 광센서(3), 상기 광센서(3)의 출력을 증폭하는 증폭부(4), 상기 증폭된 신호를 펄스형태로 파형정형하는 파형정형부(5), 광디스크(12)의 TOC 영역에 기록된 각 곡의 절대시간정보를 독출하고 각 곡의 트랙번호를 산출하여 이 트랙번호를 테이블화 하고, 각 곡의 모터회전수 및 회전각을 산출하고 테이블화 하여 메모리(9)에 저장하여 두고서, 목표트랙에 대하여 상기 메모리(9)에 저장된 상기 슬레드 모터(1)의 회전수 및 회전각에 대한 테이블을 독출하고 이를 근거로 목표트랙에 대응하는 상기 슬레드 모터(1)의 회전수 및 회전각만큼의 상기 파형정형부(5)로부터의 펄스신호를 카운트하면서 상기 모터구동부(7)를 제어하는 마이컴(6)을 구비하여 이루어진 것을 특징을 한다.To this end, the high-speed track search apparatus of the optical disk of the present invention, by the drive force of the sled motor (1), the motor drive unit 7 for driving the sled motor (1), the sled motor (1) An optical disc apparatus having a transfer mechanism 13 to 16 for transferring a pickup 17; The rotating member 2 is fixedly installed on the rotating shaft of the sled motor 1 and is composed of a rotating member 2 marked at equal intervals on one side thereof, and a light emitting element 3A and a light receiving element 3B. Of the optical sensor 3 for detecting marking, an amplifier 4 for amplifying the output of the optical sensor 3, a waveform shaper 5 for waveform shaping the amplified signal in the form of a pulse, and an optical disc 12. The absolute time information of each song recorded in the TOC area is read out, the track number of each song is calculated, the track numbers are tabulated, the motor rotation speed and the rotation angle of each song are calculated, and the table is stored in the memory 9. In order to store the target track, a table of the rotation speed and the rotation angle of the sled motor 1 stored in the memory 9 is read out for the target track, and based on this, the table of the sled motor 1 corresponding to the target track is read. Count pulse signals from the waveform shaping section 5 by the number of revolutions and the rotation angle As to the characteristics that made by having a microcomputer (6) for controlling said motor drive (7).
