Servo pattern formation via transfer of sol-gel layer and magnetic media obtained thereby |
摘要 |
A method of manufacturing a magnetic recording medium including a servo pattern, comprising steps of:(a) providing a non-magnetic substrate including at least one major surface;(b) providing a stamper having a surface with a plurality of recesses forming a negative image of a servo pattern;(c) forming a layer of a partially dried sol-gel material having a first surface in conformal contact with the recess-patterned surface of the stamper and an exposed second surface opposite the first surface;(d) urging the major surface of the substrate into contact with the exposed second surface of the sol-gel layer;(e) removing the stamper from contact with the layer of sol-gel material to expose the recess-patterned surface thereof;(f) converting the partially dried sol-gel layer to a glass-like layer while preserving the recess pattern in the surface thereof; and(f) forming on the recess-patterned surface a laminate of layers constituting a servo-patterned magnetic recording medium.
