ABSTRACT:
A drive belt release mechanism for magnetic disk drives for disengaging a drive belt from and engaging a drive belt onto a spindle drive pulley. To disengage the belt, the mechanism lifts the belt from the drive pulley and simultaneously permits the drive motor to pivot to relieve the tension in the drive belt. To engage the belt, the mechanism seats the belt on the pulley and forces the motor to a drive position which yields the desired drive tension in the belt. The mechanism is completely mechanical and manually operable.
