MOLD STRUCTURE, IMPRINTING METHOD USING THE SAME, MAGNETIC RECORDING MEDIUM AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a mold structure which is highly durable and excellent in the transfer quality of a pattern to a substrate and which allows a high-quality pattern to be transferred and formed on discrete track media and patterned media.

SOLUTION: The mold structure is provided which includes a concavo-convex pattern formed on its surface, wherein the mold structure is used for transferring the concavo-convex pattern onto an imprint resist layer formed on a surface of a substrate having a thickness of 0.3 mm to 2.0 mm by placing the concavo-convex pattern against the imprint resist layer, and wherein a thickness (Dm) of the mold structure, a thickness (Ds) of the substrate and an area (S1) of the mold structure satisfy the relationship 0.5≤(Dm/Ds)×S11/2≤100.
