A method and an apparatus for frame-by-frame recording of an RF signal on a magnetic tape uses a video tape recorder (VTR) having a dynamic tracking head. While the tape is stopped, the tracking control voltage generated by the VTR during the playback of a prerecorded tape segment is stored. The tape is then moved to the desired location and stopped. The stored tracking control voltage is then applied to the dynamic tracking head during the recording of a new set of RF signals representative of a video frame.

Method and apparatus for single frame recording on video tape

A controller for a video tape recorder (VTR) which allows a plurality of separate tape times to be cued at the selection of the operator by means of separate cue registers and corresponding cue switches operating in conjunction with a programmed controller and a tape time counter which is slaved to the VTR tape timer. The controller also causes the VTR to search for cued tape times as stored in selected ones of the cue registers and, at the option of the operator, to stop the tape at a tape time slightly prior to a selected one of the cued tape times. Digital, fine and coarse clock tape time displays are also provided for indicating the tape time, when the tape is moving, and selected cued tape times when the tape is stopped.
