Abstract

본 발명은 비디오테이프의 녹화속도제어장치에 관한 것으로, 비디오 테이프의 녹화시간제어를 위해 그 비디오테이프의 소정녹화시간의 경과시점에 형성된 천공마크와, 상기 비디오테이프에 대한 프로그램의 예약녹화모드와 예약녹화데이터를 입력하기 위한 리모콘수단, 상기 예약녹화데이터의 등록을 위한 화면표시 OSD 신호를 발생하여 CRT부상에 표시되도록 하는 OSD 발생수단, 상기 리모콘수단에서 일력되는 예약녹화데이터가 등록되는 예약데이터메모리, 상기 비디오테이프의 주행계상에 설치되어 상기 천공마크를 검출하는 천공마크검출수단, 상기 천공마크가 검출되는 시점에서 상기 비디오테이프에 대한 녹화속도모드를 변경하여 예약녹화가 수행되도록 제어하는 마이컴을 구비하여 구성되고, 상기 마이컴은 상기 천공마크가 검출되는 시점에서 현재의 녹화속도에 비해 저속의 녹화속도모드로 변경시켜 프로그램의 녹화가 수행되도록 하는 것이다.The present invention relates to an apparatus for controlling the recording speed of a video tape, comprising: a perforation mark formed at the time when a predetermined recording time of the video tape passes for controlling the recording time of the video tape, and a reserved recording mode and a reservation of a program for the video tape. A remote control means for inputting recorded data, an OSD generating means for generating an on-screen display OSD signal for registration of the reserved recording data and displaying the same on a CRT unit, a reserved data memory in which reserved recording data recorded in the remote control means is registered; A puncturing mark detection means installed on a traveling system of the video tape to detect the puncturing mark, and a microcomputer for controlling reservation recording to be performed by changing the recording speed mode for the video tape when the puncturing mark is detected; The microcomputer is configured at a time point when the puncture mark is detected. In this case, the program recording is performed by changing to a slower recording speed mode than the current recording speed.
