Abstract
Official abstract text for this publication.
A system, method and apparatus for manufacturing high density magnetic media is disclosed. A flexible mold having a very low modulus of less than about 4 GPa is made on a rigid support. The mold nano-imprints a resist material on disks for hard disk drives. The flexible mold may comprise a perfluoropolyether with urethane acrylate end groups with a low surface adhesion from which the cured resist is easily released.
First claim
Opening claim text (preview).
We claim: 1. An imprint mold for manufacturing magnetic recording media, comprising: a rigid support material that is UV-transparent and has a flat surface; a flexible mold layer on the rigid support material and having a Young's modulus of less than about 4 GPa, the flexible mold layer comprising a perfluoropolyether (PFPE) material with a urethane acrylate (UA) end group, and the flexible mold layer has a topography that forms a pattern that is precise such that one standard d…
