Latest Patents
Tefera's latest patents include an apparatus for the application of an advanced texture process. This invention addresses the removal of random scratches formed during the polishing of magnetic recording media. It also disposes of a near-circumferential texture on the media's surface, which increases recording reliability while reducing the failure rate. The invention teaches the application of a low unit load force to a pad and polishing tape combination in contact with a rotating and oscillating disk surface. This process completely removes random scratches formed by previous polishing steps. The apparatus allows for the application of a specially designed, extremely fine alumina slurry composition without producing similar size circumferential scratches at high surface speeds. As a result, the apparatus provides a smoother disk surface that is significantly more uniform than known batch process apparatus for polishing and texturing disks. This leads to increased recording reliability and improved manufacturing efficiency through reduced failures.
