Abstract
본 발명은 컴팩트디스크플레이어에서 컴팩트디스크이 트랙상의 기록정보를 재생하는 도중에 외부로부터 급작스런 충격이 가해지는 경우에는 광픽업이 서보한계를 벗어나서 이전에 재생되던 트랙영역과 무관하게 전혀 다른 트랙상의 기록정보를 독취하게 됨에 따라, 재생음의 단절 또는 엉뚱한 음의 재생이 불가피하게 된다는 문제점을 해결하기 위해 이루어진 것으로, 컴팩트디스크의 소정 트랙상의 기록정보를 재생하는 도중에 외부로부터 충격이 가해지더라도 기록트랙으로부터 이미 독취하여 버퍼링한 기록정보데이타와 일치하는 후속의 기록정보데이타를 비교검출하여 데이타를 상호연결함에 의해 정상적인 재생이 가능하도록 하는 컴팩트디스크의 쇼크프루프기능에 의한 연속재생제어방법을 제공한다.According to the present invention, when a compact disc is suddenly impacted from the outside while the compact disc is reproducing the record information on the track, the optical pickup reads out the record information on a completely different track regardless of the track area previously reproduced beyond the servo limit. In order to solve the problem that disconnection of the playback sound or reproduction of the wrong sound is inevitable, even if an external shock is applied during the playback of the recording information on a predetermined track of the compact disc, it has already been read and buffered from the recording track. Provided is a continuous playback control method by a shock proof function of a compact disc that enables normal playback by comparing and detecting subsequent recording information data that matches the recording information data and interconnecting the data.
그에 따라 본 발명은 광헤드(10)에 의해 독취되는 컴팩트디스크(D)로부터의 기록정보를 재생모드에 따라 버퍼메모리(20)를 통해 버퍼링하여 재생하는 컴팩트디스크 재생장치에 있어서; 상기 컴팩트디스크(D)의 트랙상에 기록된 기록정보데이터를 재생하기 위한 재생모드를 설정하는 단계와, 그 재생모드하에서 외부로부터의 충격이 발생되는 경우에 해당 재생상태를 일시정지시키기 위한 일시정지모드를 설정하는 단계, 일시정지모드를 해제하고 재생모드를 재설정하여 상기 TOC메모리(16)의 TOC정보를 기초로 상기 광헤드(10)가 일시정지되기 직전의 기록트랙영역으로 추종동작함에 의해 해당 기록정보데이터를 독취하는 단계, 상기 버퍼메모리(20)에 기입된 기록정보데이터와 독추된 기록정보데이터를 비교하는 단계 및, 상기 버퍼메모리(20)에 기입된 기록정보데이터와 일치하는 기록정보데이터의 후속되는 데이터로부터 그 버퍼메모리(20)에 기입하는 단계를 포함하여 이루어진 것을 특징으로 한다.Accordingly, the present invention provides a compact disc reproducing apparatus which buffers and reproduces recording information from a compact disc (D) read by an optical head (10) through a buffer memory (20) in accordance with a reproducing mode; Setting a reproducing mode for reproducing the recording information data recorded on the track of the compact disc (D), and pausing for pausing the reproducing state when an impact from the outside occurs under the reproducing mode; Setting the mode, releasing the pause mode and resetting the playback mode to follow the recording track area immediately before the optical head 10 is paused based on the TOC information of the TOC memory 16. Reading the record information data, comparing the record information data written in the buffer memory 20 with the read record information data, and recording information data consistent with the record information data written in the buffer memory 20 And writing to the buffer memory 20 from subsequent data.
