Abstract

본 발명은 영상기록재생장치의 다채널 데이타 기록재생방법에 관한 것으로, 종래에는 각각의 헤드스위칭신호의 제어를 받아 각 채널로 입력된 데이타를 기록하고 이 기록된 데이타를 재생시킬때 시스템의 헤드스위칭시간을 일치시키기 위해 시간지연부가 추가되고 메모리의 양이 증가되는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-channel data recording and reproducing method of a video recording and reproducing apparatus. In the related art, head input of a system is recorded when data input to each channel is reproduced under the control of each head switching signal and the recorded data is reproduced. There was a problem in that a time delay was added and the amount of memory was increased to match the time.

이러한 점을 감안하여 본 발명에서는 한 채널이 헤드스위칭신호를 시스템의 동기신호로 하여 데이타 기록시 에러를 방지하기 위해 동기신호패턴이 삽입된 더미데이타(Dummy Data)를 입력데이타에 부가하여 녹화데이타 포멧을 형성하고, 데이타재생시 녹화데이타에서 한 채널은 각 트랙의 선단에서, 다른 한 채널은 각 트랙의 중간에서 동기신호패턴을 검출하여 동시에 전송하여 데이타를 재생하므로써 시간의 지연이 없고 회로구성시 부품의 수를 감소시킬 수 있다.In view of the above, in the present invention, in order to prevent an error in data recording, one channel uses the head switching signal as a synchronization signal of the system, and adds dummy data in which a synchronization signal pattern is inserted to the input data to record data. When data is played back, one channel at the leading edge of each track and the other channel at the middle of each track detect the synchronization signal pattern and transmit the data simultaneously to play the data. Can be reduced.

Claims (1)

각 채널로 입력되는 데이타에 각 트랙당 동기신호블럭의 수를 일치시키기 위해 더미데이타(Dummy Data)에 동기신호패턴을 삽입하고, 각 트랙의 최선단 및 최후단의 헤드스위치신호에 의한 에러를 방지하기 위해 상기 더미데이타를 상기 입력데이타에 추가하므로써 녹화데이타 포멧으로 데이타를 형성하여 녹화하며, 상기 녹화된 데이타를 재생할때 한 채널의 헤드스위칭신호를 시스템의 동기신호로 하여 한 채널은 각 트랙의 선단에서 동기신호를 검출하고, 다른 한 채널은 각 트랙의 중간에서 동기신호를 검출하여 시간의 지연없이 각 채널로 데이타를 전송하여 재생하는 것을 특징으로 하는 영상기록재생장치의 다채널 데이타 기록재생방법.In order to match the number of sync signal blocks per track to the data input to each channel, a sync signal pattern is inserted into dummy data, and errors caused by the head switch signals at the top and end of each track are prevented. By adding the dummy data to the input data, data is formed and recorded in the recording data format, and when the recorded data is reproduced, one channel head leading signal is used as a synchronization signal of the system. And detecting another synchronization signal in the middle of each track, and transmitting and reproducing the data to each channel without time delay. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
