Abstract:
1. A method for manufacturing a magnetic recording medium by mounting a substrate for film formation on a carrier whose surface has been roughened, sequentially transporting said substrate into a plurality of connected chambers, and forming at least a magnetic film and a carbon protective film on said substrate for film formation within said chambers, wherein said method comprises a step of conducting ashing to remove an accumulated carbon protective film adhered to a carrier surface, which is performed following a step of removing a magnetic recording medium from said carrier following film formation, but prior to a step of mounting a new substrate for film formation on said carrier, and said method further comprises a step of forming a metal film on a carrier surface, which is performed following said step of conducting ashing to remove an accumulated carbon protective film adhered to a carrier surface, but prior to the step of mounting a new substrate for film formation on said carrier.
