<p>The centering and clamping device consists of six major components: a disk elevating and lowering means (13), a disk support means (16), a disk centering means (29), a disk clamping means (19), and a disk rotating means (9). In operation the disk is raised out of cartridge by the disk elevating means, and raised upward to engage the taper (29) on the spindle of the spin motor (9), moving upward until the cooperation between the taper on the next spindle and the tapering on the disk centering collar cause the disk to move laterally forward until precisely centered on the spindle. Thereafter, the continued upward movement on the disk on the elevator lifting means causes a magnet (20) located on the disk support means to come in magnetic contact with a steel plate (32) on the spindle platform, thereby securely clamping the disk to the spindle for rotation. Thereafter, the elevator means is moved downward and disconnected from the disk support means, allowing free rotation of the spindle disk and disk support means relative to a stationary elevating means. For removal, the above procedure is reversed. </p> |
