Abstract

See full text

Apparatus and method for controlling a fly height of a transducer adjacent a recording surface by adjusting a write voltage magnitude. In accordance with some embodiments, a write voltage with an initial magnitude is applied to a transducer. A write voltage change interval and a write voltage change amount are selected. The magnitude of the applied write voltage is thereafter successively reduced by the write voltage change amount over each of a plurality of successive write voltage change intervals.
