Abstract
본 발명은 ATF(Auto Track Find) 주파수를 이용하여 영상신호를 녹화 및 재생시키는 장치에 있어서, 비밀번호입력에 의해 ATF주파수를 변화시켜 녹화하고 재생시 비밀번호입력이 있는 경우에만 정상적인 재생이 가능하도록 하는 비밀번호를 이용한 녹재 방법 및 장치에 관한 것으로, 본 발명은 녹화동작시 비밀번호 입력이 있으면 기존 ATF주파수를 비밀번호 입력에 상응한 새로운 ATF주파수로 변환시켜 영상신호를 녹화시키고, 재생동작에 비밀번호와 몇 개 트랙의 ATF주파수를 변환시킨 비밀번호를 비교하여 일치할 경우만 정상적인 재생동작을 수행시킴으로써 이루어진다.The present invention is a device for recording and playing back video signals using ATF (Auto Track Find) frequency, the password to change the ATF frequency by the password input and to record and play back only when there is a password input during playback password The present invention relates to a method and apparatus for recording a tree using the present invention. The present invention records a video signal by converting an existing ATF frequency into a new ATF frequency corresponding to a password input when there is a password input during a recording operation. This is achieved by performing normal playback only if the passwords of ATF frequency are compared and matched.
