Abstract

본 발명은 기록매체의 자동탐색장치에 관한 것으로, 종래 기술은 일정시간 전후의 화면을 재생하려면 상당 시간동안 화면을 일일이 고속으로 탐색하거나 브이씨알 테이프에 특정신호를 기록하는 브이아이에스에스(VISS)나 브이에이에스에스(AVSS)기능을 갖추었어도 특정신호가 기록되지 않은 화면을 찾을 수 없어 많은 시간이 소비되는 문제점이 있었다.The present invention relates to an automatic search apparatus for a recording medium, and the related art is to replay a screen before and after a predetermined time, or to navigate a screen at a high speed for a considerable time, or to record a specific signal on a VRS tape. Even with the AVSS function, there was a problem in that a lot of time was not found because a screen without a specific signal was not found.

이러한 점을 감안하여 본 발명은 테이프에 특정신호를 기록하지 않고 원하는 화면을 일일이 고속으로 탐색하지 않으며 입력된 시간정보와 방향정보에서 캡스탄 모터의 구동시간을 산출하여 쉽고 간편하게 원하는 화면을 찾을 수 있어 시간을 절약할 수 있다.In view of this point, the present invention does not record a specific signal on a tape and does not search a desired screen at high speed one by one, and calculates a driving time of a capstan motor from the input time information and direction information, so that the desired screen can be easily and conveniently found. You can save time.
