PURPOSE:To hold in optimum the relative position of a magnetic head to a rotary magnetic sheet, by forming an aperture through which the magnetic head which performs recording and reproducing to the magnetic sheet, and a stabilizing plate opposite to the surface of the sheet which is set close to the head. CONSTITUTION:A motor 11 which revolves a magnetic sheet is attached to the lower surface of a base 12, and a cartridge support plate 14 is held horizontally on the upper surface of the base 12 via a support member 13. A rotary magnetic sheet cartridge 15 is loaded onto the plate 14 in an unloadable way and stores a flexible rotary magnetic sheet 16. The hub 17 of the sheet 16 is fitted to a motor rotary shaft 18. A head shift mechanism 19 is provided to the base 12, and a head supporter 21 is shifted in the radius direction of the sheet 16. A stabilizing plate 22 is set at the upper edge of the supporter 21 and inserted to an aperture 15b drilled through the plate 14 and the rear wall 15a of the cartridge 15. A magnetic head 23 is provided at the center of the plate 22 with a fixed amount of projection. Thus, it is possible to hold an optimum relative position between the sheet 16 and the head 23. |
