Abstract
An apparatus and method for minimizing the risk of damage to a disc surface caused by contact between a disc and a slider in a head disc assembly of a disc drive. The apparatus includes a flexure and slider which are biased away from the disc when the disc is stationary and one or more aerodynamic airfoils attached to the flexure. The airfoils are attached to the flexure and extend from the flexure at an angle relative to the disc so as to interact with an air flow caused when the disc spins to force the flexure and the attached slider to move toward the disc during operation of the disc drive.
