Magnetic recording medium

摘要

A magnetic recording medium comprises a base film consisting essentially of an aromatic polyamide and a magnetic layer formed on at least one surface of the base film, wherein the base film has a tensile Young's modulus in at least one direction of not less than 700 kg/mm<2>, a content of materials which are extractable with methylene chloride of not more than 0.5% and a dimensional change in the longitudinal direction after applying a load of 1 kg per 1 mm<2> at 100 DEG C for 10 minutes of not more than 2%.
