Method for texturing a magnetic disk silicate glass substrate
Abstract:
A glass disk is subjected to a chemical or gentle mechanical polishing step to remove microcracks or scratches in the disk surface prior to chemically texturing the disk. Thereafter, magnetic media is deposited onto the glass disk. We have discovered that by performing this pre-texturing polishing step, we can avoid the phenomenon of "linkage bumps," which could otherwise cause the resulting magnetic disk to fail a glide-type test or to cause a read/write head crash.
