Abstract
A magnetic tape recording and reproducing apparatus includes a rotatable head drum having heads and inclined with respect to a reference plane, and a pair of movable guide poles movably located in first positions respectively upstream and downstream of the head drum in a direction of travel of a magnetic tape, for guiding the magnetic tape to be wrapped helically around the head drum in a wrapping range along a tape path inclined with respect to the reference plane to allow each of the heads to scan the magnetic tape along a scanning locus to form thereon a track inclined with respect to a longitudinal direction of the magnetic tape in a recording mode at a normal speed. In a fast-forward or fast-reverse playback mode, one of the tape guide poles is displaced along the reference plane and locked in a second position other than the first positions to change the wrapping range of the magnetic tape. The tape path is shifted so that the formed track on the magnetic tape will be brought into conformity with the scanning locus of each of the heads when the magnetic tape is transported at a higher speed in the playback mode.
