Abstract
A slider having a slider body is provided for actively controlling a fly height of the slider relative to a data storage disc. A first plurality of beams are affixed to a back surface of the slider body. The beams are disassociated from one another and are constructed of deformable material. Each beam, in response to an applied electrical control signal is deformable in a first dimension parallel to the back surface of the slider body. Deformation of the first plurality of beams in response to an applied electrical control signal affects slider fly height by changing one of slider body crown and cross curvatures to a greater extent than along the other. In accordance with other embodiments, multiple layers of deformable beams are attached to a slider. In yet other embodiments, piezoelectric material layers having anisotropic properties are substituted for beam layers.
