Abstract
A disk drive includes a gear transmission system disposed with a casing. The gear transmission system includes first and second gears, a driving plate having a right serrated portion meshed with the first gear, and a left serrated portion disposed adjacent to and facing the third gear. Rotation of the second gear in clockwise and anti-clockwise directions alternately results in movement of the driving plate in left and right sides of the casing, which, in turn, results in engagement and disengagement of the third gear with the left serrated portion of the driving plate, alternately. The driving plate further has an open-ended slot formed at the left end of the driving plate and adjacent to the left serrated portion in such a manner to provide resilience when the left serrated portion is engaged with the third gear.
