An elongated tape recording and reproducing system wherein a longitudinal control track is prerecorded on the edge of the tape either with a recording transducer, such as a magnetic head, as part of the system or off-line. After the control track is recorded, oblique video tracks are recorded on the tape with two video transducers or heads spaced 180 DEG apart and traveling obliquely to the recorded control track. During reading of the video information, one obliquely traveling video head reads the address on the longitudinal recorded control track while the other obliquely traveling head reads the video information on the obliquely recorded video track. After the video heads have traveled 180 DEG , their roles are reversed. That is, the video head which was reading the video information on the obliquely recorded track, now reads the address on the longitudinal recorded control track. In addition, the spacings between the address data on the control track serve as servo information for maintaining the tape and video heads in alignment.
