ABSTRACT:
A magnetic tape apparatus in which data is recorded on or reproduced from a magnetic tape when the magnetic tape is run on a rotary drum, includes a tension regulating unit which regulates a tension of the magnetic tape when the magnetic tape is run, the tension regulating unit pressing the magnetic tape at a first position in a tension-applying direction. A slack preventing unit exerts a rotating force on the tension regulating unit at a second position such that the rotating force exerted at the second position acts on the tension regulating unit at the first position to further press the magnetic tape in the tension-applying direction, thus preventing a slack of the magnetic tape from being produced when changing a tape winding direction of the magnetic tape.
