Abstract

본 발명은 광디스크 재생장치에 관한 것으로, 광디스크 재생장치를 회전하는 스핀들 모터의 초기 가동 시정수를 일정시간으로 고정시켜 스핀들킥을 함으로써 모터의 특성 및 소자의 편차에 의해 발생되는 시간지연의 문제점이 있었던 종래의 문제점을 개선하기 위해 본 발명은 스핀들 모터의 초기가 동시 정수를 결정하기 위하여 스핀들 모터로부터의 회전신호를 검출하고, 검출된 회전신호를 기준으로 소정의 파형을 생성하여 상기 스핀들 모터의 1회전 주기구간동안 내장된 카운터를 이용하여 소정 클럭으로 카운트하여 기설정된 1회전 주기 클럭 범위를 만족하면, 위상동기루프(PLL)로 인입하도록 제어함으로써 스핀들 모터의 초기가동 시정수를 각 상황에 따라 가변적으로 설정하므로 PLL제어로의 인입이 빠르고, 안정적으로 스핀들 모터의 구동을 제어할 수 있다.The present invention relates to an optical disc reproducing apparatus, and has a problem of time delay caused by the characteristics of the motor and the deviation of the device by performing a spindle kick by fixing the initial operation time constant of the spindle motor rotating the optical disc reproducing apparatus to a predetermined time. In order to solve the conventional problem, the present invention detects the rotation signal from the spindle motor to determine the simultaneous constant of the initial stage of the spindle motor, and generates a predetermined waveform based on the detected rotation signal to rotate the spindle motor once. If the counted clock is satisfied by using the built-in counter during the period, and the preset one-turn cycle clock range is satisfied, the initial operation time constant of the spindle motor can be variably changed according to the situation by controlling to enter the phase-locked loop (PLL). It is possible to insert into the PLL control quickly and stably to drive the spindle motor. There can control.
