Abstract:
An apparatus for recording and reproducing a video signal to and from a magnetic tape, comprising:a controller to selectively control recording of each frame signal of the video signal in such a way that the frame signal is divided into N (N being an integer of two or more) slant tracks on the magnetic tape at a standard tape speed in a standard mode, the frame signal is divided into N/2 slant tracks at a tape speed Â½ of the standard speed in Â½ speed mode, or the frame signal is divided into N/2 slant tracks at a tape speed &frac13; of the standard speed in &frac13; speed mode, and to control reproduction in such a way that the frame signal is reproduced at a tape speed n (n being a speed coefficient and nâ‰ 1) times the tape speed at which the frame signal has been recorded in at least either the Â½ or the &frac13; speed mode, the speed coefficient n being set to a value included in a predetermined range or given by at least either an equation (1) or (2): n=N(2m+1)/2iâˆ’1)Â±2/(2iâˆ’1)â€ƒâ€ƒ(1) n=Nm/iÂ±1/iâ€ƒâ€ƒ(2) where a variable i is an integer from 1 to 10, and a variable m is an integer; andwherein the variable i is set to 1 for the speed coefficient n that is (Nâˆ’2) or more, whereas the variable i is set to 2 or more for the speed coefficient n that is less than (Nâˆ’2).
