Abstract

In a magnetic disc drive (10) including a disc (12) having a magnetic surface and supported for rotation on a spindle (11), a spindle motor (13) for driving the spindle, a transducer head (14), a head support structure (15) for moving the head along the disc surface, and a speed control circuit (22) for controlling the speed of the spindle motor, there is disclosed a method for contaminant purging and head loading. The spindle motor (13) is operated at a speed significantly above the normal operating speed and filtered air is circulated past the head (14) and the disc surface. The head is loaded and caused to fly on the disc surface and the spindle motor speed is then reduced to the normal operating speed.
