Abstract
Provided is a disk loading apparatus which includes a frame base on which a spindle motor is mounted. The apparatus includes a disk loading structure that loads a disk on the spindle motor, a plurality of sliders operating in connection with a loading lever, and a plurality of gears transferring the motive power to the plurality of sliders. The apparatus also includes a plurality of shafts to which the gears are coupled, and a plurality of slider guide walls that guide movement of the plurality of sliders. According to various aspects, the shafts and the slider guide walls are formed integrally with the frame base.
Claims15
A disk loading apparatus comprising:
