Claims
- 1. A method of manufacturing a recording medium, the method comprising:forming a protective overcoat on the magnetic recording medium having a distribution of servo-marks therein; applying a fluoropolyether capable of cross-linking on the protective overcoat; and polymerizing the fluoropolyether to form a cross-linked fluoropolyether topcoat lubricant directly on the protective overcoat to obtain a substantially planarized media surface.
- 2. The method according to claim 1, comprising:texturing a surface of a non-magnetic substrate to form a distribution of pits or indentations therein to function as the servo-marks in the magnetic recording medium.
- 3. The method according to claim 1, wherein the fluoropolyether comprises a plurality of —(CaF2aO)n— repeating units, wherein subscript a is independently in each repeating unit an integer of from 1 to about 10 and n is an integer from 5 to about 80.
- 4. The method according to claim 3, wherein fluoropolyether comprises one or more acrylate groups.
- 5. The method according to claim 1, comprising polymerizing the fluoropolyether by ultraviolet radiation.
- 6. The method according to claim 1, comprising applying a fluoropolyether capable of cross-linking on the magnetic recording medium by dip coating the magnetic recording medium.
