ABSTRACT:
Method and apparatus for texturing a substrate for use in a magnetic recording disc. A texturing pad used in the invention has inner and outer coaxial regions, with the outer region being more compressible. When the pad and a substrate are rotated about parallel, offset axes, and pressed against one another in the presence of a particle slurry, the inner, less compressible region of the pad produces a deeper-groove texturing on an inner annular surface region of the disc.
