Video signal recording apparatus with track centering using crosstalk detection and third odd multiple field recording

A video signal recording apparatus for recording an input composite video signal which is to be recorded on closed loop tracks which are successively formed on a rotary recording medium, said input composite video signal including at least picture information and a synchronizing signal, said video signal recording apparatus comprising:

• recording and reproducing means for recording and reproducing the input composite video signal on and from the rotary recording medium which undergoes one revolution in one field of the input composite video signal, said input composite video signal using horizontal and vertical scan in conformance with a 2:1 interlaced scanning;
• feeding means for intermittently feeding said recording and reproducing means;
• driving circuit means for supplying a driving signal for driving and controlling said feeding means;
• gating means for passing and supplying to said recording and reproducing means as an output signal of said gating means said input composite video signal in a recording mode, and for passing and supplying as an output signal of said gating means a reproduced signal which is reproduced from the rotary recording medium by said recording and reproducing means in a reproducing mode;
• track position detecting means for obtaining an actual track pitch between an intended track which is to be newly formed on the rotary recording medium and an adjacent pre-recorded track adjacent to the intended track when said recording and reproducing means is scanning the intended track based on a signal component which is reproduced as crosstalk from the adjacent pre-recorded track and for supplying to said driving circuit means an error signal which is obtained by comparing the actual track pitch and a predetermined track pitch;
• and
• control means for controlling operating timings of said gating means and said driving circuit means,
• said control means generating control signals based on said input composite video signal and supplying the control signals to said gating means and said driving circuit means to record a signal amounting to one field on each track of the rotary recording medium so that out of two mutually adjacent tracks making up a track pair, a signal related to one of odd and even fields out of signals which are related to two consecutive fields and constitute a picture is recorded on one track of the track pair and a signal related to another of even and odd fields out of signals which are related to two consecutive fields and constitute a picture is recorded on another track of the track pair to thereby record signals amounting to one frame on the track pair, the two signals recorded on the track pair having a time difference of M fields which is three or more odd integral multiple of one field.
