Abstract

It is proposed that load bearing particles in a magnetic disk coating be selected to minimize their catalytic reaction with lubricants applied to the disk surface. The use of lubricants on state of the art direct access storage device (DASD) magnetic media is required to provide long term stability of head flight. It is known that low flying heads quickly crash on unlubricated surfaces. Furthermore, lubrication of a disk causes an increase in abrasion resistance by at least an order of magnitude, and often more.
