Helical scanning magnetic recording/playback device having multiple pairs of playback heads and recording heads

摘要

Two playback heads A1 and A2 having the same azimuth theta and having a track width W11 equivalent to about 1.5 times the track width W2 of the recording head are paired to form a pair of heads. These playback heads A1 and A2 paired to form a pair of heads are arranged so as to read one recording track T1 simultaneously in the condition with a gap of about one track pitch TP in the track width direction. Data of all recording tracks are thus read correctly without tracking during playback.
