Abstract
A magnetic or optical disk load/unload device for automatically centering and clamping a disk to the spindle of an information storage device. The apparatus is comprised of a toggle arm, a toggle arm rotating device, a support base, a support hub having a centering stem and a concentric annular steel ring disposed on its mating surface, a member for clamping the hub to the support base, a spindle having a centering hole on its mating surface and a concentric magnetic material ring on its mating surface, and a spindle rotating motor. In operation, the toggle arm is rotated from a first bent position causing the support base hub and disk located thereon to advance toward the spindle, the hub slidably retained on the base by a of clamping member activated by a cam assembly. Upon full extension of the toggle arm, the hub and disk are centered on the spindle, clamped to same by the magnetic and steel rings. The toggle arm continues on to a second bent position, causing the support base to retreat from the support hub, the clamping member having been released. At this point the spindle, disk and hub are free to rotate. For unload, the above described procedure is reversed.
