Claim 1
Independent Claim
109 words
A tracking control arrangement for a magnetic recording and reproducing device, the arrangement comprising: a magnetic tape; drive means for driving said tape; at least two reproducing magnetic heads (lA, 1B) for simultaneously scanning different slant tracks (TRa, TRb) recorded on said tape, said magnetic heads (lA, 1B) having respective different azimuth gaps (g 1 , g 2 ); phase detecting means (56, 104) for detecting a phase error between signals reproduced by said two magnetic heads (lA, 1B); and controlling means (57, 106) for controlling the positions of said tracks (TRa, TRb) and said magnetic heads (lA, 1B) relative to one another in dependence on said phase error.
