Abstract

An integrated, unitary micro-burnishing head structure for use with the surface of rigid magnetic recording media. In one type of embodiment, the proposed head structure includes a single elongate flexure body to one end of which is joined a media-contacting abrader head which may take any one of several different preferred shapes. In another embodiment, plural elongate flexure bodies are disposed in a comb-like array carrying abrader heads at one set of free ends, and joined adjacent their opposite ends through a common joinder structure.
