Abstract
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.
