Abstract

A piezoelectric bender is used to dynamically adjust the preload on the slider air bearing surface of a magnetic recording head/ suspension assembly. This allows changes in the head flying height to optimize head/disk interface characteristics during file operations such as start/stop cycles, crash stops, and idle periods.
