The disk burnishing process is conducted with a contact flying burnishing head wherein the leading edge of the burnishing head is disposed above the surface of the disk, while the trailing edge of the burnishing head makes contact with the surface of the disk. The contact flying configuration of the burnishing head is obtained by controlling the rotating disk RPM in conjunction with the burnishing head design characteristics. In the contact flying burnishing process, the burnishing edges of the several burnishing pads of the head are disposed at different heights relative to the disk surface, such that the leading burnishing pad edges are higher than the trailing burnishing pad edges. In this configuration, high asperities are trimmed by the burnishing pads while low asperities are not. Thus, a disk is properly burnished for subsequent hard disk drive performance with a minimum of surface debris being created by the burnishing process.
