ABSTRACT:
A linear drive apparatus for the load mechanism of an information storage disk drive system utilizes over-center pivotable link pin connections between a linear drive lever and counter-rotating drive cranks used for raising and lowering a disk spindle drive into and out of engagement with the storage disk. The over-center pivoting link pins provide an idle period for the spindle lift mechanism while the same linear drive lever powers the cartridge positioning apparatus utilized for loading and unloading the disk cartridge under power from the disk drive system.
