ABSTRACT:
A forced flow of cooling air through a computer housing is created during operation of a specially designed CD ROM drive operatively disposed in the housing. The drive has a bladed carrying structure which supports a compact disc and is rotationally driven with the supported disc. Driven rotation of the bladed carrying structure creates the forced flow of cooling air within the housing without requiring additional space for a separate cooling fan therein. In two illustrated embodiments of the bladed carrying structure the created cooling air flow is generally parallel to the rotational axis of the compact disc, and in a third embodiment of the bladed carrying structure the created cooling air flow is generally transverse to the rotational axis.
