<p>PROBLEM TO BE SOLVED: To obtain a good reproduced picture without causing cross talk and a noise in a magnetic tape in which a bending track is recorded and formed by constituting a device so that a height of a rotation locus plane of a magnetic head can be adjusted. SOLUTION: This device has first and second tilt means, the first tilt means tilts a central axis of a magnetic head by an angle in which rotation locus planes of magnetic heads H1 , H2 are coincident for a recorded locus of a magnetic tape. The second tilt means makes a position regulation plane of the magnetic tape coincide with a reference periphery position of the magnetic tape in a state in which relative relation of positions between the a recorded locus of the magnetic tape and rotation locus planes of magnetic heads H1 , H2 is held. And preceding to the first tilt means, a bending track is compensated by varying heights of rotation locus planes in a start end side and a terminal of a winding range of the magnetic tape for a drum DA by compound operation of operation varied in the reverse direction each other and operation varied in the same direction.</p> |
