发明名称 Magnetic recording medium and method for producing the same
摘要 It is a magnetic recording medium for which favorable values for all of reproduced output, noise level and error rate can be obtained, and which is also superior in terms of storage stability. A magnetic recording medium (10), which has a configuration in which a magnetic layer (3) comprised of a maghemite thin film containing cobalt is formed on a tape-shaped substrate (1) comprised of aromatic polyimide, and in which the substrate (1) is 3 to 10 mum in thickness, and 5 to 30 nm in its ten-point average roughness (SRz) of the surface on which the magnetic layer (3) is formed, and the magnetic layer (3) is 10 to 50 nm in thickness, 0.1 to 3.0 nm in center plane average thickness (SRa), and 2,000 to 4,000 Oe (158,000 to 316,000 A/m) in in-plane coercivity, is made.
