Abstract
The present invention is to provide a magnetic tape recording/reproducing device capable of accurately positioning a magnetic tape relative to a magnetic head to thereby improve recording/reproduction characteristics to or from the magnetic tape even when the running direction of the magnetic tape is inverted between forward and reverse directions. First guide rollers are provided so as to swing between a first inclined position and a second inclined position along a tangential direction of the magnetic tape partially wound on roller portions and, where the first inclined position is such that allowing upper flanges to reside on an upstream side of the lower flanges in the tape running direction, and the second inclined position is such that allowing the upper flanges to reside on a downstream side of the lower flanges in the tape running direction. The first guide rollers are respectively provided with drive means for allowing the first guide rollers to swing between the first and second inclined positions.
