Abrading > Abrading Process > Side Face Of Disk Side Face Of DiskSide Face Of Disk patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.07/06/06 - 20060148386 - Method and device for manufacturing substrate for magnetic disk, and method of manufacturing magnetic disk A magnetic polishing method capable of easily and satisfactorily polishing the inner peripheral end face of a circular hole (1) at the center part of a disk substrate (2) even if the diameter of the circular hole is reduced. By this method, a large quantity of disk substrates with stable ... 12/01/05 - 20050266778 - Carrier heads, planarizing machines and methods for mechanical or chemical-mechanical planarization of microelectronic-device substrate assemblies Planarizing machines, carrier heads for planarizing machines and methods for planarizing microelectronic-device substrate assemblies in mechanical or chemical-mechanical planarizing processes. In one embodiment of the invention, a carrier head includes a backing plate, a bladder attached to the backing plate, and a retaining ring extending around the backing plate. The ... 11/10/05 - 20050250426 - Method and an element for surface polishing A surface polishing method in which a workpiece having at least one surface for polishing is set into rotation and has said surface pressed against a polishing element that is driven with motion in rotation or in translation, wherein said surface of the workpiece presents points that are situated outside ... 06/30/05 - 20050142990 - Texturing of magnetic disk substrates A method for texturing a substrate for a magnetic disk comprises abrading the substrate using nano-sized diamond particles (e.g. having a diameter less than or equal to 20 nm). A magnetic layer is then deposited over the substrate. Even when the texture is extremely smooth (e.g. less than about 2.2 ... ### FreshPatents.com Support |
