Multiple filter for use in a disc drive |
摘要 |
A layer of air adjacent a disc surface in a disc drive is subject to contamination by particles. The disc is spun, inducing a radial air flow and a recirculation air flow. A particle impact layer around an outer disc edge traps a first portion of the particles carried by the radial air flow. A filter adjacent the outer disc edge includes a recirculation filter element that traps a second portion of the particles carried by the recirculation air flow. STL 10692
