Patent ID: 8899957

Claim:
A system for imprint mold manufacturing of magnetic recording media, comprising: an imprint mold having a rigid support material that is UV-transparent in a wavelength range of 250 to 400 nm and has a flat surface, and a flexible mold layer on the rigid support material and having a modulus of at least 10 MPa, and a Young's modulus of less than about 4 GPa, the flexible mold layer comprising a fluorohydrocarbon polymer; placing the imprint mold in contact with a substrate having a void-free resin formation to form a topography on the substrate; and the flexible mold layer has optically visible alignment targets that are placed in contact and aligned with the substrate based on the optically visible alignment targets, and the flexible mold layer has a topography that forms a pattern that is precise such that one standard deviation of patterned dimensions is less than 1 nm.
