| abstract | [PROBLEMS] To provide a magnetic recording medium capable of obtaining a sufficient C / N in short-wavelength recording even when a magnetoresistive reproducing head having a narrow track width is used. SOLUTION: In a magnetic recording medium having one or more layers on one surface on a nonmagnetic support, and the uppermost layer being a magnetic layer mainly composed of a ferromagnetic powder and a binder, the magnetic layer has a dry thickness of 100 nm. And the weight saturation magnetic flux density (Bs / 4π), which is the ratio between the saturation magnetic flux density of the magnetic layer and the coating film density. ρ) is set to 120 Am 2 / kg or more. Thereby, good output and C / N can be obtained. Further, the Mrt value of the magnetic layer is 2.4 nTm or less, and / or the squareness ratio is 0.4. 85 or more. This gives better results. Further, the average major axis length of the magnetic powder used for the magnetic layer is set to 80 By setting it to nm or less, better results can be obtained. |
