Abstract:
A method of manufacturing a patterned magnetic recording medium, comprising steps of:(a) providing a non-magnetic substrate including at least one major surface; (b) providing a stamper having a recess-patterned surface comprising a negative image of a pattern of recesses to be formed in said medium; (c) forming a layer of a partially dried sol-gel material (â€œmaterialâ€ ) having a first surface in conformal contact with said recess-patterned surface of said stamper and an exposed second surface opposite said first surface; (d) placing said major surface of said substrate in contact with said exposed second surface of said layer of material; and (e) removing said recess-patterned surface of said stamper from contact with said first surface of said layer of material; whereby said layer of material is transferred to said major surface of said substrate, such that said second surface of said layer of material is in contact with said major surface of said substrate, and said first surface of said layer of material is exposed and includes a positive image of said pattern of recesses.
