ABSTRACT:
The invention relates to a method of recording a television signal of the kind in which the signal is recorded on a relatively slowly moving tape in a plurality of inclined tracks by a plurality of recording heads carried at the periphery of a head wheel rotating at a relatively high speed in a plane non-parallel to the direction of tape motion. The head wheel executes m complete revolutions for each n complete television pictures, where the ratio m
is non-integral, and control signals having a frequency of 1
of the picture frequency are recorded along a longitudinal control track by a fixed head. For recording signals according to the 625 line European standard, m is chosen to be 25 and n is chosen to be 2. For the U.S. 525 line standard, m is 21 and n is 2. In both cases 25 lines per track are recorded.
