ABSTRACT:
When a disk drive is running, airflow is generated in the disk drive. The disk drive includes a tray and a housing. A plurality of through-holes are disposed on the tray, and the housing accommodates the tray therein. While airflow flows over the through-hole, noise is generated. Walls are formed on the rim of the through-hole to reduce this noise. A sponge for absorbing noise is adhered on the inner top portion of the housing for absorbing noise. As holes are located on the front end of the tray for guiding airflow, noise is reduced to a lower level.
