摘要： A magnetic recording medium is provided that includes a recording layer having recording elements formed as convex portions and a filling material filled within the concave portions between the recording elements. The medium is highly reliable and has a surface less liable to damages when a magnetic head contacts the surface, so that good recording/reproducing characteristics are ensured. The magnetic recording medium includes a recording layer formed in a predetermined concavo-convex pattern over a substrate and having recording elements formed as convex portions in the concavo-convex pattern and a filling material filled within the concave portions between the recording elements. The filling material is substantially composed of Si and O, and the ratio of the number of O atoms to the number of Si atoms is equal to or more than 1.5 and less than 2.
