Optic disk drive vibration absorbing device

Abstract

An optic disk drive includes a casing, the inside of which a driving unit is arranged. The driving unit includes a motor for rotating a disk driving wheel mounted therein. A disk holding arm is pivoted to the casing and extends above the casing to define a spacing therebetween for removably receiving a disk tray supporting an optic disk thereon to position the optic disk between a disk holding wheel rotatably provided on the disk holding arm and the disk driving wheel. The disk holding wheel holds the optic disk against the disk driving wheel to allow the optic disk to be driven by the motor. A vibration absorbing device includes a plate-like body having a front extension provided on a front edge of the body and two rear extensions provided on an opposite rear edge of the body. The front and rear extensions all have a free end on which a vertical flange is provided and the two rear extensions are spaced from each other so that the vertical flanges define a triangle to tightly fit over and thus be secured on the motor. The plate-like body further has two anchoring arms extending therefrom to be fixed to the casing so as to provide a rigid connection between the casing and the motor and thus increase the overall structural rigidity which in turn enhances the positional precision so that optimized performance can be achieved.
