Abstract: PURPOSE: To degauss a perfectly packed pancake by means of a fast cycle time by permitting a recording carrier to be insertable into a coil with a lift-up device in an axial line direction. CONSTITUTION: The magnetic recording carrier 8 is carried to a degaussing device 1 in an arrow direction on a conveyor belt 7. The device consists of a solenoid, providing cylindrical coil windings, and the coil windings are driven with a charged capacitor 6. When the recording carrier 8 reaches the device 1, the conveyor belt 7 is stopped, and the recording carrier 8 is lifted-up into the inner space of the device 1 by the lifting device 5. Therefore, the recording carrier 8 is coaxially arranged in the coil, the capacitor 6 discharges with the coil windings at this time and the recording carrier 8 is perfectly and efficiently degaussed by an alternating magnetic filed which occurs in a form of a damped vibration.

Abstract: PURPOSE: To simply, effectively press a hub to a winding element and to accurately hold a tensioning means by providing a plurality of elastic elements uniformly distributed on a periphery over an inner periphery of the hub, and forming the element in a shape of a bent arm. CONSTITUTION: The hub 1 has an outer part having a cylindrical surface 12 for winding a magnetic tape, an inner cylindrical part 3 and a radial web 13 disposed therebetweeen. A plurality of elastic elements 2 are extended from the part 3 and formed in an arm-like state radially bent. Further, radially protruding protrusions 7 are provided at ends of the elements 2. The hub 1 is compressed in winding on the hub 1 of a magnetic tape. Accordingly, before winding, the hub 1 is brought into contact with the hub holder 6 only at the protrusions 7. Meanwhile, when the tape is completely wound on the hub 1, the hub 1 is held by the elements 2 and the protrusions 7, and the hub 1 is brought into contact with the winding shaft 9 or the holder 6.
