Abstract
An inlet to a disc drive's filter chamber is tapered to converge along most or all of its length so as to reduce drag and increase inflow volume and velocity. This accelerates the removal of particles from the disc drive's sealed chamber, reducing the likelihood of particle-induced data transfer errors or media damage.
