Abstract

PURPOSE:To realize a slidably-contacting state of a sheet and a head, having high reliability, by forming a window part into which the head and a sheet guide plate are inserted, on a sheet jacket housing. CONSTITUTION:A rotary magnetic sheet 8 is stored in a sheet jacket housing 7 freely rotatably, and a window part 9 into which a head for recording and reproducing to the sheet 8, and a guide plate 43 to the sheet, which has been placed in the adjacent position of the head are inserted respectively is formed on the housing 7. As a result, the sheet surface can be guided exactly by the guide plate 43 irrespective of the state that a sheet jacket 6 has been mounted to a rotary shaft 45.
