Abstract

PURPOSE:To enable to perform the cleaning of attached dust simply, by changing the flow of clean air and increasing the flow than usual. CONSTITUTION:In the enclosure 11 of the magnetic disc unit, the magnetic disc pack 1, magnetic head 2, carriage 3 and electromagnetic actuator 4 are contained. The blower 6 is provided at the lower side of the bottom of the enclosure 11, and after the lower side of the bottom of the enclosure 11, and after the air delivered from this blower 6 is removed for the dust at the first filter 7, is reaches the electromagnetic change-over valve 8. At normal operation of the unit, the electromagnetic valve 8 is charged over to the second filter 9, and the air flows in the enclosure 11 through the second filter 9. Immediately after the power application of the unit, the electromagnetic valve 8 is changed over to the bypass pipe 10 automatically, air is delivered to the duct 12, and clean air increased for the flow remarkably blows out the dust attached to each part in the flow path.
