ABSTRACT:
A first reproduction signal is reproduced by use of a first pair of magnetic heads having first and second azimuth angles and arranged around a rotary drum at two opposing angular positions 180 degrees away from each other, respectively. A second reproduction signal is reproduced by use of a second pair of magnetic heads having first and second azimuth angles and arranged around the rotary drum at two opposing angular positions 180 degrees away from each other, respectively. A video signal is reproduced based on the first and second reproduction signals. The magnetic tape travel speed is set to a value (2n+1.+-.m/M) times higher than that in recording, where n is an integer of 0 or more; m and M are a natural number, respectively; T.gtoreq.12/(P+Q) (T: an integer) when m/M=2k/T; and P>0, Q>0.
