Publication number: 20090255808Abstract: Aspects comprise sputtering targets comprising a base material carrier provided with a recessed pattern, such as a looping trench, to receive a more precious material to be sputtered during deposition processes. The looping trench can have a cross-section of varying depth based on an expected variation in the magnetic field. The more precious material is provided at least in the trench, for example by hot pressing, and also can be pressed into a layer across an entirety of a surface of the carrier. During operation, the desired deposition of the precious material can occur from the trench area. Thus, a higher percentage of the precious material in the target is used, reducing inventory costs. The base material can be selected based on characteristics of the more precious material, and based on goals including reducing diffusion of base material into precious material and galvanic reactions.Type: ApplicationFiled: April 9, 2009Publication date: October 15, 2009Applicant: Seagate Technology LLCInventor: Jeffrey Shane Reiter

Patent number: 6835290Abstract: A system and method for reducing and controlling the number of defects due to carbon inclusions on magnetic media is disclosed. A diamond like carbon protective layer is deposited on magnetic media using a rotary cathode target assembly. The target and cathode are cylindrical in shape and are mounted on holder that allows the target and cathode to rotate while holding a magnet fixed. The target surface is periodically swept in through a plasma which sputters off the surface of the target. This prevents the build up of redeposited material on the target and consequently keeps the target surface cleaner. The reduction of redeposited material on the target surface reduces the number of unwanted particulates which are ejected from the surface, manifesting themselves as disk defects.Type: GrantFiled: February 13, 2003Date of Patent: December 28, 2004Assignee: Seagate Technology LLCInventors: Jeffrey Shane Reiter, Stephen Eric Barlow, Zhiwei Cai
