摘要: A method for texturing a disc substrate, and a particle slurry for use in the method. The slurry includes two populations of different-size particles, preferably one population containing particles in a 3 micron size range, and a second population containing particles in a 1 micron size range. The particles, when used to abrade the surface of a disc, create a surface texture characterized by a low peak/peak-to-valley ratio.
