Abstract
A magnetic recording and reproducing apparatus with a positioning mechanism for a tape guide drum is provided. The positioning mechanism includes first and second actuators which changes the position of the tape guide drum relative to a direction of travel of a magnetic tape during reproduction for orienting rotary magnetic heads to follow tracks formed on the magnetic tape perfectly if the tracks are curved undesirably. The first actuator is designed to turn the tape guide drum to orient a portion of a rotation plane of the rotary magnetic heads at a tape-entering position where the magnetic tape enters the tape guide drum in a first direction and a portion of the rotation plane at a tape-leaving position where the magnetic tape leaves the tape guide drum in a second direction opposite the first direction. The second actuator is designed to turn the rotation plane of the rotary magnetic head at the tape-entering position and the tape-leaving position in the same direction.
