ABSTRACT:
A hard disk drive dynamically establishes a pitch static attitude (PSA) of a slider as appropriate to be higher during load and unload and lower during operation. Also, the PSA may be dynamically established during operation as a function of slider radial position and/or internal disk pressure and/or fly height to adjust slider fly height and/or contact stability. A PSA bias mechanism such as a piezoelectric layer can be coupled to the slider suspension to bend the flexure of the suspension to achieve PSA adjustment.
