Abstract
Two playback heads A,and A,having the same azimuth &thgr; and having a track width W,equivalent to about 1.5 times the track width W,of the recording head are paired to form a pair of heads. These playback heads A,and A,paired to form a pair of heads are arranged so as to read one recording track T,simultaneously in the condition with a gap of about one track pitch T,in the track width direction. Data of all recording tracks are thus read correctly without tracking during playback.
