Magnetic recording medium, a method of manufacturing the same, and a magnetic storage device using the magnetic recording medium |
摘要 |
A magnetic recording medium according to the invention includes a nonmagnetic substrate made of a polymer resin, the nonmagnetic substrate having been treated to improve an adhesion characteristic thereof; an adhesive layer on the nonmagnetic substrate, a nonmagnetic undercoating layer on the an adhesive layer; a magnetic layer above the nonmagnetic undercoating layer; a protection layer above the magnetic layer; and a liquid lubricant layer on the protection layer. A method of manufacturing the magnetic recording medium described above includes the steps of: treating a nonmagnetic substrate to improve an adhesion characteristic thereof; forming an adhesive layer on the nonmagnetic substrate, the adhesion thereof having been improved; forming a nonmagnetic undercoating layer on the adhesive layer; forming a magnetic layer above the nonmagnetic undercoating layer; forming a protection layer above the magnetic layer; and forming a liquid lubricant layer on the protection layer. A magnetic storage device according to the invention mounts thereon the magnetic recording medium described above.
