Abstract
The design and implementation of adaptive LS estimation and fault recovery procedure for PZT-actuated milli-actuator were presented. We confirmed that the adaptive estimation method identified the milli-actuator DC-gain precisely and the fault recovery procedure detected the degradation of milli-actuator gain during track-following data reading/writing operation.
