Rotating magnetic sheet device

Abstract

Abstract PURPOSE:To constantly make head touch of a magnetic head equal and to reduce a space of a regulation board by disposing movably a regulation board radially of a magnetic sheet and attaching so as to interlock with a head carriage. CONSTITUTION:When a head carriage 38 is fed by the rotation of a lead screw, a pin 76 integrated with a regulation board holder 70 engages with a pin 78 constituted integrally with the head carriage 38, so that a regulation board 52 moves together with the head carriage 38. As a result, a magnetic head 42 corresponds to the regulation board 52 and moves horizontally and performs a magnetic recording and reproducing on a magnetic sheet 12. According to such constitution, the head touch of the magnetic head 42 is constantly fixed and a picture quality is not changed in the outer periphery and the inner periphery of the magnetic sheet 12. The length corresponding to a stroke for moving the regulation board 52 and the magnetic head 42 is not required and the size of the regulation board 52 can be reduced.
