| titleOfInvention | Magnetic recording medium |
| abstract | (57) [Summary] (Correction) [Purpose] To provide a magnetic recording medium having excellent high frequency characteristics, good signal overwriting characteristics, and excellent light transmittance. A bottom layer 2 having at least one non-magnetic layer containing two or more kinds of non-magnetic powders having different sizes on a non-magnetic support 1, and a top layer comprising a magnetic layer containing a ferromagnetic powder. 4 is laminated in this order, and when the average major axis length of the ferromagnetic powder in the uppermost layer 4 is less than 0.25 μm and the crystallite size by the X-ray diffraction method is L 0 , L 0 ≦ 250 (Å) and the crystallite sizes of two or more kinds of non-magnetic powders having different sizes in the non-magnetic layer 2 by the X-ray diffraction method are L 1 , L 2 , ..., L When N-1 and L N , 0 <L N <L N-1 <... <L 2 <L 1 ≦ 700 (Å) and 5 × 10 (3-N) / (N + 2) ≦ L N ≦ 7 × 10 (3-N) / It was set to N (Å). |
