摘要： A method for manufacturing a magnetic recording medium that has a sufficiently flat surface and includes a recording layer having a concavo-convex pattern that provides favorable accuracy of recording and reproduction. The manufacturing method includes the steps of: forming a lower non-magnetic film over a recording layer having a concavo-convex pattern; and forming an upper non-magnetic film on the lower non-magnetic film to fill concave portions 34 of the concavo-convex pattern. A bias power is applied to an object to be processed at least in the step of forming the upper non-magnetic film, and no bias power or a smaller bias power than the bias power applied in the step of forming the upper non-magnetic film is applied in the formation of the lower non-magnetic film.

A sample object is digitized to sample data formed by digital data. The sample data is compressed into compressed sample data according to a predetermined data format. There is calculated a difference data amount between a data amount of the compressed sample data and a data amount of reference data formed by digitizing and compressing a reference sample object in the same manner as the sample object is processed. Which of a plurality of predetermined numerical ranges the difference data amount belongs to is identified. A predetermined process is determined which is associated with the identified numerical range in advance as a next process to be carried out next.
