(57) [Problem] To provide a magnetic recording medium suitable for a thin tape-shaped medium. SOLUTION: The magnetic layer has a thickness of 2 μm or more, The projections have 5,000 to 9000 protrusions / mm 2 on a plane 10 nm from the center plane in the surface roughness measurement, and the projections 500 to 9000 on a plane 30 nm from the center plane in the surface roughness measurement. 2,000 oxides / mm 2 , a thickness of 3 μm or less, a linear absorption coefficient in transmission of a single light of 800 nm of 2.2 to 3.5 μm −1 , and chromium oxide (CrO 2 ) It contains two or more magnetic powders including magnetic powder. |
