摘要： 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.

摘要： A method of manufacturing a magnetic recording medium comprises steps of providing a non-magnetic substrate for a magnetic recording medium, the substrate including at least one major surface; forming a layer of a sol-gel on the at least one major surface; forming a pattern, e.g., a servo pattern in an exposed surface of the layer of said sol-gel; and converting the layer of sol-gel to a glass or glass-like layer while preserving the pattern in an exposed surface of said glass or glass-like layer. Embodiments of the invention include magnetic media including a patterned glass or glass-like layer formed from a layer of a hydrophilic sol-gel with the pattern embossed therein by means of a stamper having a hydrophilic surface including a negative image of the pattern.
