Abstract

A technique is provided to produce a bump or asperity of a known height on a magnetic recording disk for use in glide height testing. The technique involves drilling and tapping partially through a disk to produce a bump asperity on the opposite surface of the disk. The disk may or may not be coated with a magnetic recording material at the time the asperity is produced.
