titleOfInvention | Magnetic recording media |
abstract | (57) [Problem] To provide a magnetic recording medium which suppresses an increase in noise as much as possible regardless of storage for a long period of time and which has higher durability and corrosion resistance. SOLUTION: In a magnetic recording medium in which a magnetic coating is provided on one surface of a support, the magnetic coating mainly contains iron and cobalt, has a major axis particle diameter of 0.25 μm or less, and an axial ratio of 4-8. And the weight ratio of cobalt to iron is 8 to 5 0% by weight of a needle-shaped alloy magnetic powder, and the magnetic coating film has a center line average roughness of 0.004 μm or less, and the total thickness of the magnetic recording medium is 14 μm It is characterized by the following. |
