Claims

[Scope of utility model registration request]

A center core is arranged at the center of rotation of the magnetic sheet, and a magnetic metal plate is integrally bonded to one end surface in the axial direction of this core, and the drive shaft of the magnetic recording and reproducing device is inserted into the core. The metal plate has a shaft insertion hole, and the metal plate has a bent piece for detecting the seat rotational position whose tip faces the other end face of the core in the axial direction. A flange portion is formed, one surface of the flange portion serves as a sheet bonding surface, and 1, a position reference is provided in which the outer surface of the metal plate is perpendicular to the drive shaft and parallel to the magnetic recording surface of the sheet. A rotating magnetic sheet device characterized by a surface.
