ABSTRACT:
A magnetic recording and reproducing apparatus, e.g., a video tape recorder for recording and reproducing digital video signals etc., is intended to reliably perform a tracking control even when recording tracks are formed with high density. A first pilot signal having a large azimuth loss and a second pilot signal without azimuth loss are recorded in a recording track, and a rough tracking control operation and a fine tracking control operation are executed on the basis of the second pilot signal and the first pilot signal respectively.
