Claim:
A low noise optical disk drive comprising: a top cover; a bottom base, and a containing space being defined between the top cover and the bottom base; a playing mechanism assembled in the containing space and capable of being drawn out for holding a disk, wherein when the playing mechanism is holding the disk in an operating state, the rotation of the disk generates a main air current within the containing space and therefore produces noise; and a noise absorbing device installed in the containing space on a bottom surface of the top, cover opposite the playing mechanism for absorbing the noise produced from the main air current, the noise absorbing device comprising a plurality of triangular-shaped protruding teeth spaced at intervals and protruding into the containing space; wherein when the main air current flows through the noise absorbing device, the main air current is divided into a plurality of air currents of different directions by the protruding teeth so as to reduce the noise.
