A disk clamping system receives two different types of removable data storage disks. Disks supported within a cartridge include a metal ring or metal segments circumferentially disposed about a centering hole. The metal is attracted to a magnet disposed in a turntable portion of a spindle, adjacent a hub portion of the spindle, so the disk is drawn down to the turntable without use of an external clamp. Disks not supported within a cartridge, or supported within a cartridge providing access for a clamp, are pressed down to the turntable by magnetic attraction between the clamp and a second magnet in the top of the hub. In both cases, magnets and metal elements can be interchanged, if so desired. |
