Abstract:
Provided are a master recording medium and a method of manufacturing the master recording medium. The master recording medium includes: a plate; and a magnetic layer which is formed on the plate for magnetically transferring of a servo pattern that is to be formed on a magnetic recording medium. The method of manufacturing a master recording medium includes: engraving a polymer layer by nano imprinting to form an engraved pattern corresponding to a servo pattern to be formed on a magnetic recording medium; forming a magnetic layer which fills in the engraved pattern of the polymer layer; forming a back plate layer on the magnetic layer; and performing processing to expose the servo pattern on a surface of the magnetic layer that is opposite a surface of the magnetic layer on which the back plate layer is formed.
