Magnetic recording medium |
abstract |
The present invention provides a magnetic recording medium in which a magnetic layer is directly provided on at least one surface of a base film mainly composed of an aromatic polyamide, and has a projection number N a (10) ( 10 mm / mm 2 ) or more on the surface of the magnetic layer. , Number of projections N a (50) (50 mm / mm 2 ) or more in height, and number of projections N a (10) 'or more (mm / mm 2 ) in height of 10 nm or more on the same surface of the magnetic layer installation side of the base film are as follows. Satisfy the expression at the same time.n n n 2 × 10 4 ≤N a (10) ≤2 × 10 7 n n n 0 ≤N a (50) ≤5 × 10 4 n n n -0.9 ≤ (N a (10) -N a (10) ') / N a (10) '≤ 0n n n The magnetic recording medium of the present invention uses an aromatic polyamide film having a high rigidity as a nonmagnetic support, and the surface properties of the surface of the magnetic layer and the surface of the base film are controlled within a specific range, so that the overall thickness is reduced and also as a product having a recording capacity. It has excellent running durability and high reliability for recording and reading data, and is suitable for computer data recording. |
