Abstract
A delay time adjusting system comprises a comparing circuit for comparing levels of reproduced frequency modulated signals from a pair of rotary heads which simultaneously scan over a magnetic tape, where the rotary heads have gaps of mutually different azimuth angles, a head selecting circuit responsive to an output signal of the comparing circuit, for selectively producing the reproduced signal from the rotary head having the greater level, a signal processing circuit for obtaining a reproduced video signal from the reproduced signal which is selectively produced from the head selecting circuit, a variable delay circuit for delaying the reproduced video signal from the signal processing circuit by a delay time, and a delay control signal generating circuit for variably controlling the delay time of the variable delay circuit so that the variable delay circuit produces a reproduced video signal in which reproduced horizontal synchronizing signals have a constant period.
