| abstract | [PROBLEMS] To provide a magnetic disk for high-density recording which has excellent electromagnetic conversion characteristics, particularly high-density recording characteristics, does not cause data loss due to destruction of a magnetic layer during head running, and does not cause blocking. thing. SOLUTION: In the magnetic disk, a substantially non-magnetic lower layer is formed on a support and a magnetic layer formed by dispersing a ferromagnetic metal powder or a hexagonal ferrite powder in a binder is formed on the lower layer. The thickness of the magnetic layer is 0.02 to 0.5 μm, the ten-point average height Rz of the magnetic layer surface measured by a non-contact type surface roughness meter is 20 nm or more and 50 nm or less, and the number of protrusions whose height measured by AFM is 20 nm or more is 1 A magnetic disk having a size of × 10 5 / mm 2 or more and 2 × 10 6 / mm 2 or less. |
