Abstract

본 발명은 디지털/아날로그 동시 기록재생장치에 관한것으로, 종래에는 영상신호를 기록재생함에 있어 해당 방식에 따른 영상신호만을 기록 또는 재생함으로써 시청을 원하는 다른 방송 프로그램을 볼수없는 문제점이 있었다.The present invention relates to a digital / analog simultaneous recording and reproducing apparatus. In the related art, in recording and reproducing a video signal, there is a problem in that other broadcasting programs that are desired to be viewed cannot be viewed by recording or reproducing only a video signal according to a corresponding method.

이러한 점을 감안하여 본 발명에서는 두 방식의 영상신호를 수신함에 따라 디지털신호 및 아날로그신호를 동시에 기록재생하도록 헤드를 장착하여 구성한다. 이에따라, 기록재생시 헤드를 스위칭하여 두방식의 영상 신호를 기록하고 재생함에 따라 원하는 방식의 영상을 재현할 수 있다.In view of this point, in the present invention, the head is mounted to record and reproduce the digital signal and the analog signal simultaneously when receiving the video signals of both systems. Accordingly, when recording and reproducing, the head is switched to record and reproduce two types of video signals, thereby reproducing an image of a desired method.
