Abstract:
A video tape recorder having a single clock frequency recording means for recording tracks of a first type video signal having a first field frequency and a second type video signal having a second field frequency onto a magnetic tape; wherein the tracks corresponding to said first type video signal and said second type video signal differ in length by an amount greater than an end track-length error and less than twice said end track-length error; said end track-length error being the margin-of-error distance from each edge of said magnetic tape for recording a track; said video tape recorder including means for recording each track such that a reference point located substantially in the center of each track of a video signal is recorded at a corresponding point located substantially in the center of the magnetic tape such that the difference in length at each end of the tracks between tracks corresponding to said first type video signal and said second type video signal is less than said end track-length error.
