Producing magnetic recording layer in hard disk, comprises arranging a magnetic recording layer on a substrate, and forming a discrete trace recording structure on the substrate

摘要

Production of a magnetic recording plate comprises arranging a magnetic recording layer on a substrate, and forming a discrete trace recording structure on the substrate. Independent claims are also included for: (a) magnetic recording layer produced by the above process; (b) process for the production of a magnetic recording layer; (c) device comprising a unit for arranging a Ni-P layer on a substrate, and a unit for forming a discrete trace recording structure on the substrate; and (d) disk running gear.
