Abstract

A magnetic disc in a cartridge is ventilated to keep a data containing surface portion thereof substantially free of particulate materials. A recirculating gas path includes apertured conduits for supplying gas jets completely across the portion as the disc is rotating in an enclosure. An orifice removes gas from the enclosure. A fan circulates the gas removed from the enclosure through the orifice and supplies the circulated gas back to the apertured conduits. Magnetic heads are positioned relative to the orifice and an inlet for the gas jets such that the gas has laminar flow as the gas passes the magnetic heads so the gas flow does not affect the position of the heads relative to the disc portion. The recirculating path includes filters for removing particulate materials from the recirculating gas.
