PURPOSE:To make slow the relative velocity of a rotary magnetic sheet against a guide, to prevent the rotary magnetic sheet from damaging, to protect the rotary magnetic sheet from the attaching of foreign matters, and to prevent the occurrence of a drop-out by forming a roller shaped guide which rotates in the same direction as the rotating direction of the rotary magnetic sheet. CONSTITUTION:The surface waving of a magnetic sheet 1 occurred when a magnetic head 2 is pressed on the magnetic sheet 1 can be prevented by pressing the both sides of the magnetic head 2 with two roller shaped guides 5 and 5 which rotate by itself with the same linear velocity as the magnetic sheet 1. Thereby, the relative velocity at an opposing contact part 6 between the magnetic sheet 1 and the guides 5 and 5 becomes zero, and a flaw due to a contact between the magnetic sheet 1 and the guides 5 and 5 can be reduced. And a reproducing output with a high output and good quality can be obtained.
