P-HDI-09 CONTACT BURNISHING FOR HEAD WEAR REDUCTION

Abstract

To reduce head wear to develop future hard disk drives, we introduced a new burnishing technique (Contact Burnishing : CB) using a hemispherical diamond slider and compared pin wear on disk surfaces with and without the burnishing. The results showed that the pin wear was reduced by the introduction of the burnishing technique. The reason of wear reduction by CB was considered to be the reduction of asperity heights.
