Abstract:
A method of manufacturing a magnetic recording medium having a non-magnetic substrate, at least one backing layer formed on said non-magnetic substrate, and a magnetic layer formed on said backing layer, wherein:said non-magnetic substrate is a glass substrate;said backing layer is a Cr--Mo alloy comprising chromium and molybdenum;said magnetic layer is a Co--Pt alloy comprising cobalt and platinum;said method comprising the steps of:forming said Cr--Mo alloy with molybdenum in an amount of 8-80% by sputtering;forming said Co--Pt alloy with platinum in an amount of 5-30% by sputtering; andkeeping said non-magnetic substrate at a temperature between room temperature and 400.degree. C., inclusive, on forming each of said backing and said magnetic layers for providing a lattice distance in (110) surface of said backing layer approaching a lattice distance in (002) surface of said magnetic layer.
