A contact burnishing head is described for memory surfaces of computer memory disks. The operating surface of the burnishing head is defined by a regular pattern of diamond-shaped protrusions. In one embodiment, a ramp face is provided along the leading edge of the head in order to prevent large asperities in the disk surface from interfering with proper burnishing. In another embodiment, two opposed edges of the head are provided with ramp faces so that a single head design can be used to burnish either the upper or the lower surface of a computer disk.
