(57) [Summary] [PROBLEMS] A high track density, in which a servo signal is provided, Provided is a high-density magnetic recording medium having a high linear recording density, having excellent electromagnetic conversion characteristics, high output, high resolution, a high S / N ratio, and excellent running durability. SOLUTION: In a magnetic recording medium provided with a servo signal, at least one undercoat layer and a magnetic layer are formed in this order on a non-magnetic support, and the thickness of the magnetic layer is 0.20 μm. Hereinafter, the magnetic powder contained in the magnetic layer is composed of a ferromagnetic iron-based alloy powder containing Co and a rare earth element, When the average major axis length L is 0.15 μm or less, the average major axis length L And the shortest recording wavelength λ is in a relationship of L / λ ≦ １ ／, and the magnetic layer contains carbon black having a particle size larger than the thickness of the magnetic layer. |
