ABSTRACT:
A tape position control apparatus for video tape recorders is mainly composed of a tape control device which functions to control the movement of a video tape, a count circuit for counting the number of control pulses reproduced from the video tape, a segment data memory for storing segment data indicating the number of control pulses from the tape for the top or beginning of each segmented video information which is recorded on the video tape with reference to segment number of the segmented video information, an input device for requesting to search one of the segmented video information by generating a segment number, a comparison circuit for comparing currently counted number stored in the count circuit with the top segment data for the requested segment number, and a command signal generating circuit for generating command signals to be supplied to the tape drive control circuit in order to search for the top of the requested video information.
