ABSTRACT:
A burnish head comprising a slider body having a single crystal diamond attached to a rear portion flies above the disk surface at a relatively low flying height when the disk is rotated at a high angular velocity. The diamond produces acoustic waves that cut or crack disk asperities, resulting in a highly-smooth disk surface suitable for near-contact or in-contact magnetic recording.
