<p>PROBLEM TO BE SOLVED: To prevent a magnetic head from being shortened in service life and being damaged by warping, the sticking cut scraps, etc., of a recording medium by providing a simulated magnetic head or a roller on the upstream side from the magnetic head. SOLUTION: A simulated head 31 and a back roller 41 the rollers 4 and 41 or the roller 4 and a roller support 43 is provided with a magnetic track between on the upstream side from the magnetic head 3. The contact surface part of the head 31 has a shape almost equal to the head 3, and proper pressure is applied to the head 3 by the roller 41. By such a constitution, the cut scraps, etc., are eliminated, and the warping 11, etc., is restored to a nearly flat surface by passing the recording medium 1 through a magnetic recording/reproducing device, and the matter that the surface of the magnetic head is scratched to be injured, and the magnetic head is shifted from an attached position is reduced. Thus, the service life is prevented from being shortened, and the cause of the fault is reduced.</p> |
