摘要： 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.

摘要： Position control apparatus is provided for a magnetic information device that uses a magnetic recording medium having a readable series of pulses recorded along a serial path thereon. For example, the magnetic information device could be a video tape recorder and the magnetic recording medium could be a video tape with a series of control pulses recorded upon it. The position control apparatus includes a reading device for serially reading the recorded pulses and for producing a corresponding train of output pulses, a counter for counting the output pulses and for providing a count value corresponding to a position on the recording medium, a memory for settably storing a value corresponding to a desired position on the recording medium, a comparator for comparing the count value from the counter and the stored value from the memory, and a search device which, upon selective operation thereof, is operative to cause the reading device to serially read the recorded pulses until a predetermined relation is obtained between said two values to be compared by the comparator.
