Abstract
Method and circuit for recording and detecting a program end signal which enable a new program to be recorded after the end of previously recorded program on a video tape by searching an end portion of the previous program. The circuit includes a consecutive recording switch for selecting a consecutive recording mode for searching for an end portion of a program which has been previously recorded on a tape and consecutively recording a program, a program end recording unit for outputting a control pulse at a reference duty cycle which is generated from a servo system, modulating the control pulse at a predetermined duty cycle when a stop signal, is inputted, while delaying a stop signal, outputting a predetermined number of control pulses for indicating an end of program, and thereafter outputting said stop signal, and a program end detecting unit for outputting a recording signal for operating the video cassette tape recorder in a recording mode when no control pulse is detected from the tape or after the program end indicating pulse is detected upon selection of the consecutive recording mode by the consecutive recording switch.
