A magnetic recording medium having a magnetic layer on at least one side of a base film which is a stretched film of styrene polymer having a high degree of syndiotactic configuration or a composition thereof or a laminate film containing the stretched film, wherein linear expansion coefficient is not more than 5 x 10<-><5>/ DEG C and static friction coefficient is not less than 0.3 and not more than 1.0 is disclosed. The magnetic recording medium has good sliding properties, smoothness, heat resistance and moisture resistance, is excellent in dimensional stability to temperature and moisture, and has good coersive force, thus can be highly densified. |
