ABSTRACT:
Structure for maintaining a magnetic head at a constant flying height over a magnetic disk surface. Electromechanical transducers cooperate with structure of a negative pressure head slider mechanism to keep the slider out of contact with the magnetic disk when the disk is not rotating, and to move the head to within a constant flying height over the disk surface when the disk is rotating at a sufficient constant speed. The structure of the negative pressure head slider may be such as to maintain the slider at the constant flying height even when drive voltage is not applied to the transducers, so long as the magnetic disk is rotating at a constant speed.
