INTEGRAL BUSH-DISK CLAMP FOR MAGNETIC DISK MEMORY Russian patent published in 1999 - IPC

FIELD: information accumulation equipment, magnetic disk memories. SUBSTANCE: magnetic disk memory has an integral body for a bush, clamp and rotor, which is recommended for manufacture by pressure moulding of plastic material, The bush comprises a hollow cylindrical part for bearings and a flanged part supporting the single disk. Flexible clamping pins on the upper surface of the flange catch the disk through its central hole. The pins automatically align the disk with the bush. The bush also functions as a body of the motor rotor of the disk rotation. EFFECT: reduced manufacturing cost of magnetic disk memory, improved counteraction to mechanical impact, reduced disk bending. 8 cl, 8 dwg
