Dynamic method and apparatus for controlling head fly characteristics in a disk drive

Abstract

A dynamic method and apparatus are provided for controlling head fly characteristics in a disk drive. A plurality of charge surfaces is provided with a transducer head slider assembly. At least one head fly characteristic is monitored during operation of the disk drive. An identified current head fly characteristic is compared with a predefined head fly characteristic to identify a difference value. A charge and potential of the plurality of charge surfaces are dynamically controlled responsive to the identified difference value. Dynamically controlling the charge and potential of the plurality of charge surfaces enables both dynamically controlling flyheight of the transducer head slider assembly and dynamically controlling angles of the transducer head slider assembly relative to an associated disk surface.
