ABSTRACT:
Embodiments of the present invention are directed to an apparatus and method for guiding bypass reentry flow through filter integrated in a bypass channel sidewall in a hard disk drive. The method provides a bypass channel for directing airflow away from a first portion of a disk of the hard disk drive and toward a second portion of the disk of the hard disk drive, the bypass channel comprising an inner bypass channel sidewall and an outer bypass channel sidewall. The method further provides a first filter portion integral with the inner bypass channel sidewall, the filter portion for filtering a first portion of the airflow directed toward a third portion of the disk of the hard disk drive wherein a second portion of said airflow is directed toward the second portion of said disk drive.
