Abstract: PURPOSE:To enable high density recording by using a biaxially oriented poly-p- phenylene sulfide film having specified characteristics as a principal constituent layer and by providing a specified degree of matching and a specified dimensional stability index. CONSTITUTION:A biaxially oriented poly-p-phenylene sulfide (PPS) film contg. units represented by structural formula I by >=70mol% of the repeating units is used as the principal constituent layer of a base film, and a ferromagnetic layer is formed on the PPS film to manufacture a magnetic recording medium. At this time, deg.C degree of matching Cp and dimensional stability index Ds are provided. Units of m-phenylene sulfide, ether or the like account for the remaining
