ABSTRACT:
A "Winchester" type magnetic disk memory apparatus is disclosed that includes an air recirculation system in the clean chamber that assures positive pressure at all points of potential leakage. In conjunction with that feature, the head assembly positioning mechanism is located outside the clean chamber to provide substantial improvements in contamination control. Significant advantages in the manufacture and maintenance of the apparatus also result.
