<p>PURPOSE:To obtain stable electromagnetic conversion characteristic. CONSTITUTION:A tape guide roller 51 for guiding a magnetic tape T is constituted of the tape guide roller provided with a roller flange 52 at the end part of one side for positionally controlling the magnetic tape T to one side in the breadthwise direction of tape, and this tape guide roller 51 is always energized to the tape guiding side of the roller flange 52. By this arrangement, the movement of the magnetic tape T is controlled in the breadthwise direction of tape in such a manner that upper/lower end edges of the tape are abutted on each end surface of the roller flange 52 of the tape guide roller 51 and a reel flange 16c of a tape reel 16 when the tape is driven, therefore, the generation of the winding disturbance of the magnetic tape T is prevented at the time when the tape is driven.</p> |
