PROBLEM TO BE SOLVED: To provide a magnetic tape which makes high-density recording by a perpendicular magnetic recording system possible. SOLUTION: The magnetic tape 10 is constituted by laminating a ground surface layer 15 for improving corrosion resistance, a magnetic recording layer 16 for magnetically recording information, a protective layer 18 for protecting the magnetic recording layer 16 against deterioration and wear, and a lubricating film 20 for improving traveling durability and corrosion resistance by imparting lubricity in this order on one surface of a flexible and management base 14 formed to a long-size form. The magnetic recording layer 16 consists of a rare earth transition metal ally of which the coercive force in a direction perpendicular to the film plane ranges from 1,500 to 4,000 Oe.
