Claims (3)

입력장치(2)에 버퍼메모리(3)와 기록부(4)를 연결하여 광디스크(1)상에 데이터를 기록하고 재생부(5)에 비교회로(6)와 에러율검출기(7)를 연결하여 상기 광디스크(1)상에 데이터를 재생시키는 회로에 있어서, 상기 입력장치(2)에 버퍼메모리(8)를 상기 버퍼메모리(3)와 병렬로 연결하고 상기 재생부(5)에 버퍼메모리(9)를 연결하여 상기 비교회로(6)에 접속하며 상기 에러율검출기(7)에 인버터(10)를 연결하여 상기 버퍼메모리(3)에 접속함과 아울러 상기 버퍼메모리(8)에 접속하여서 된 것을 특징으로 하는 광디스크구동장치.The buffer memory 3 and the recording unit 4 are connected to the input device 2 to record data on the optical disc 1, and the comparison circuit 6 and the error rate detector 7 are connected to the reproducing unit 5 to the above. In a circuit for reproducing data on an optical disc (1), a buffer memory (8) is connected to the input device (2) in parallel with the buffer memory (3), and a buffer memory (9) to the reproducing section (5). Is connected to the comparison circuit (6), the inverter 10 is connected to the error rate detector (7), the buffer memory (3) and the buffer memory (8). Optical disc drive device. 제1항에 있어서, 비교회로(6)는 입력데이터(B)와 재생데이터(A)의 비교타이밍을 맞추어 상기 두신호의 불일치 횟수가 상기 에러율검출기(7)의 기준의 검출값보다 작을 경우는 정상기록으로 간주되어 버퍼메모리(8)가 동작하여 정상데이터를 광디스크(1)에 기록하고, 상기 횟수가 검출값보다 클 경우는 오기록으로 간주되어 버퍼메모리(3)가 동작하여 재차 광디스크(1)에 데이터를 기록하는 것을 특징으로 하는 광디스크 구동장치.2. The comparison circuit (6) according to claim 1, wherein the comparison circuit (6) adjusts the comparison timing of the input data (B) and the reproduction data (A), and when the number of inconsistencies between the two signals is smaller than the detection value of the reference of the error rate detector (7). It is regarded as normal recording, and the buffer memory 8 operates to record normal data on the optical disc 1, and if the number of times is larger than the detected value, it is regarded as an incorrect recording and the buffer memory 3 is operated again to thereby operate the optical disc 1 again. The optical disk drive apparatus, characterized in that to record data. 제1항에 있어서 비교회로(6)에서 입력데이터(B)와 재생데이터(A)를 비교하는 동안 새로운 입력데이터가 버퍼메모리(8)에 입력됨으로서 데이터 처리 속도가 향상되는 것을 특징으로 하는 광디스크 구동장치.An optical disc drive according to claim 1, wherein new input data is input into the buffer memory (8) while the comparison circuit (6) compares the input data (B) with the reproduction data (A). Device. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
