摘要
A disk drive unit includes a housing enclosing a spindle and motor assembly, a number of magnetic data storage disks and a number of transducer heads. Each magnetic data storage disk includes a surface with a coarsely textured head landing zone and a finely textured data storage area. The coarse texture is applied over the fine texture in the landing zone without forming a step in elevation at the boundary. A method for texturing the magnetic disk includes first applying a fine texture to both the data storage area and the landing zone, and then applying a coarse texture to the landing zone only. Texturing apparatus includes peripheral disk clamps permitting axial compliant movement when the opposed disk surfaces are engaged by balanced, pneumatically biased abrading tools. A free abrasive slurry is introduced to pads carried by the tools.
