35MASTER MEDIUM FOR MAGNETIC TRANSFER INCLUDING RESIN SUBSTRATE INTEGRALLY MOLDED WITH MICRORELIEF OR MICRORECESS PATTERN ABSTRACT OF THE DISCLOSURE A master medium for use in magnetic transfer ofinformation to a magnetic recording medium. The mastermedium includes a resin substrate which is integrallymolded with a microrelief or microrecess pattern beingformed on a surface of the substrate and representing theinformation; and a magnetic layer formed on themicrorelief or microrecess pattern. Preferably, thesubstrate and the microrelief or microrecess pattern areformed by injection molding using an original platehaving a microrecess or microrelief pattern, or the 2Pmethod using the original plate and an ultraviolet-curingresin.
