Abstract: In one implementation, a method and apparatus is provided for determining an active fly height setting for a transducer head from samples collected from a proximity sensor during less than a single revolution of a disc. Implementations of the method and system use adaptive discrete wavelet transform parameters generated from the collected samples to determine an active fly height setting for a transducer head.
