Patent number: 8946835Abstract: A planarization process may planarize a media disk that has data trenches between data features and larger servo trenches between servo features. A filler material layer is deposited on the media disk and provides step coverage of the trenches. The filler material has data recesses over the data trenches and servo recesses over the servo trenches that must be removed to produce a planar media surface. A first planarization process is used to remove the data recesses and a second planarization process is used to remove the servo recesses.Type: GrantFiled: September 14, 2012Date of Patent: February 3, 2015Assignee: Seagate Technology LLCInventors: Yuan Xu, Wei Hu, Justin Jia-Jen Hwu, Gene Gauzner, Koichi Wago, David Shiao-Min Kuo
