摘要： 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.

摘要： A spindle motor structure includes a rotor, a stator accommodated mainly inside the rotor, and an internal roof magnet located on an inner roof surface of a rotor bell of the rotor. The internal roof magnet further has an inner rim and an outer rim. The inner rim is located projection-wisely within a range of a hollow shaft of the stator. The outer rim is located projection-wisely between an internal peripheral surface of the rotor bell and an inner edge of a coil of the stator. By providing the internal roof magnet inside the rotor bell, a magnetic field to immerse the stator can be generated to damp out possible operational noises and disturbance upon the spindle motor.

摘要： A disk drive includes a gear transmission system disposed within a casing. The gear transmission system includes first and second gears, a driven plate having a first serrated portion meshed with the first gear, a second serrated portion facing a third gear, and first and second guiding slots. A lifting frame has two couplers slidably engaging with the slots in the driven plate. Rotation of the third gear alternately in opposite directions results in movement of the driven plate in right and left sides of the casing, which, in turn, results in lifting of the frame to an upper reading position, in which, a resilient pushing arm of the lifting frame abuts against the driven plate to provide resilience between the second serrated portion and the third gear.
