| 摘要 |
The present invention provides a method for inspecting deposition characteristics of a deposit on the surface of a protective film predominantly containing carbon of a magnetic recording medium, which medium includes a disk and the protective film formed on the disk, the disk including a non-magnetic substrate, a non-magnetic undercoat layer, and a magnetic layer, the layers being formed on the substrate, wherein the method includes comparing a predetermined threshold with the extraction amount of an inspection gas component and/or a compound component formed so as to contain the inspection gas component, the gas component and/or the compound component being extracted with an inspection solvent after the magnetic recording medium is allowed to stand in an atmosphere of the inspection gas component; a process for producing a magnetic recording medium in which the extraction amount is equal to or greater than the threshold, the extraction amount being obtained through the inspection method; and a magnetic recording medium produced through the production process. |
