<p>PURPOSE:To always perform satisfactory magnetic recording and reproduction, to simplify structure and to suppress a cost by pressurizing a separable air intake contact with a compressed air supplying part arranged at the downstream in the moving direction of a slider, and spraying compressed air on a tape. CONSTITUTION:On the slider 9, a compressed air spray part 1 that is a pressing force pressing part is arranged in parallel with a tape guide 12, and presses the tape 21 on a guide drum 25 side by a variable pressing force when the tape 21 is brought into contact with the circumference of the guide drum 25 by the tape guides 12 and 13. At the downstream in the moving direction of the slider 9, the compressed air supplying part 5 is arranged, and when the slider 9 is moved and the tape guide 12 is connected, an elastic tube opening 6 is pressurized contact with a supplying opening 5a, which forms a path communicated to an air flow path 9b'. Therefore, it is possible to adjust a tape floating quantity by pressing the tape on the drum side by spraying gas from the compressed air spray part 1. In such a way, magnetic recording and reproduction can be performed satisfactorily, and also, the cost can be suppressed by simplifying the structure.</p> |
