PURPOSE:To prevent the occurrence of a crease on a medium by providing a tension providing mechanism in one end part of a cylindrical supporting body to which a hub supporting body which positions and supports a hub member is inserted and detaining a double-faced tape on this mechanism and adhering the tape to the hub member in a centering state. CONSTITUTION:A slide chip position control body 52 is rotated, and a detaining pin 54 provided on a slide chip 50 is positioned to a detaining hole 53 provided on an upper peeling paper 23 of a double-faced adhesive tape 4 to attach the tape 4, and the control body 52 is rotated to give a tension by energizing of a compression coiled spring 51, and a lower peeling paper 60 is peeled thereafter. The tape 4 is positioned to the side face of a base end part 44 of a spacer part 42. A spacer 58 and a medium 5 are set onto the upper peeling paper 23 remaining on a cylindrical supporting body 40 and the chip 50. The medium 5 has the inside face positioned to the outside face of a front end part 43 of the spacer part 42. A hub member 2 is pressed to a hub supporting body 41 again to adhere the medium 5 to the tape 4. The medium 5 is adhered and is detached together with the hub member 2 when the hub member 2 is detached from the supporting body 41, thus obtaining a magnetic disc. |
