<p>PURPOSE:To lessen the damage of an edge part of a magnetic tape when the magnetic tape is wound over 200 deg. to a rotary drum in the M loading model. CONSTITUTION:A magnetic tape is wound in the range not smaller than 200 deg. to a rotary drum. The rotary drum is inclined an angle theta2 in the -X'-axis direction in the coordinate axis X'-Y' obtained by rotating an angle theta1 in the counterclockwise direction a virtual coordinate axis X-Y of a reference plane 2 to which the rotary drum is projected. The rotary drum is constituted of a rotary drum 1 mounted H1mm lower than the reference plane and a pair of leading guide blocks 3, 4 driven by double-joint link mechanisms 34, 35. The magnetic tape is wound to the rotary drum facing a cassette in a manner to be approximately bilateral symmetric to the Y-axis. Impedance rollers 41, 42 are fixedly set which are in touch with the magnetic tape between a vertical guide roller and an inclined guide post when the tape is completely drawn out by the leading guide blocks.</p> |
