Abstract
A magnetic disk positioning device for loading a magnetic disk onto a disk drive comprises a driving pin projecting from a turntable. The driving pin, which is positioned within a triangular hole defined within the disk drive turntable, is capable of moving in both the radial and circumferential directions. Upon loading, the driving pin initially slips into a rectangularly shaped hole provided in the disk hub. As the disk rotates further, the driving pin is clamped by a slanting side of the triangular hole and two sides of the rectangular hole. By securing the position of the driving pin, the invention enables a magnetic disk to be accurately and consistently positioned at the desired point within the disk drive and so allows more precise recording and replaying.
