Rotating-head video signal recording apparatus

A video signal recording apparatus, comprising:

• (a) a rotating cylinder provided with a plurality of rotating heads having different rotational phases;
• (b) recording means for sequentially supplying said plurality of rotating heads with a video signal having interlaced video information;
• and
• (c) control means for controlling a phase difference between said rotating cylinder and a vertical synchronizing signal of said video signal on the basis of a relationship between said plurality of rotating heads and said video signal, said control means always including a plurality of target phase differences.

A video signal recording apparatus, comprising:

• (a) a rotating cylinder provided with a plurality of rotating heads having different rotational phases;
• (b) recording means for sequentially supplying said plurality of rotating heads with an n:1 interlaced video signal, where n is an integer equal to at least 2;
• and
• (c) control means for controlling a phase difference between said rotating cylinder and a vertical synchronizing signal of said video signal, said control means capable of shifting a target phase difference for a 1/n horizontal scanning period of said video signal.

A video signal recording apparatus, comprising:

• (a) means for receiving a video signal having interlaced fields;
• (b) recording means for recording said video signal on a recording medium sequentially using a plurality of rotating heads;
• and
• (c) control means for controlling phases of said rotating heads, said control means including a switching means for switching a target phase difference between a rotating head and a vertical synchronizing signal of said video signal recorded by said recording means for a period corresponding to a phase difference between a vertical synchronizing signal and a horizontal synchronizing signal of each field.
