Abstract
In a disk file, a mechanism places the magnetic transducer into and out of a transducing position by using the air flow generated in the file by the rotating disk. The magnetic head is biased out of contact with the magnetic disk media. As the disk media starts rotating and building up an air flow within the file, a nozzle directs this air against the slider to urge it towards the media. At running speed, the head is positioned at a flying height by negative air pressure generated by the slider flying over the media. The air flow nozzle can be a funnel shape formed in the arm assembly used to position the sliders over a track in the disk media or a knife edge assembly can be used to gather and direct the air flow towards the suspension and slider.
