Abstract
A magnetic recording and reproducing apparatus for recording and reproducing a video digital signal suitable to a narrowed track pitch having two magnetic heads with the same azimuth angle arranged with an overlapped area to reproduce the same track, and a tracking servo executing phase control such that a center of a reproducing track is brought to a center of the overlapped area of the two magnetic heads. Reproduced signals of the two magnetic heads are compared so that the reproduced output of the magnetic head having a good on-track condition is always selected to improve a tracking margin without increasing crosstalk disturbance from adjacent track.
