| titleOfInvention | Magnetic recording medium |
| abstract | A magnetic recording medium having good electromagnetic conversion characteristics, particularly high-density recording characteristics, excellent running durability, no concern about head corrosion and medium deterioration, and excellent storage stability at high temperatures and humidity. To provide. A magnetic recording medium having a lower layer mainly containing a nonmagnetic inorganic powder and a binder on a support, and a magnetic layer containing at least a ferromagnetic powder and a binder on the magnetic recording medium. Diol compound having a layer thickness of 0.02 to 0.2 μm, an average major axis length of the ferromagnetic powder of 20 to 60 nm, and a binder of the magnetic layer and lower layer having a cyclic structure and a long alkyl chain And a diisocyanate compound-containing polyurethane resin and no vinyl chloride resin, and the number of protrusions on the surface of the magnetic layer is 30 to 500/100 μm 2 and the number of protrusions of 25 nm or more is the total number of protrusions. The magnetic recording medium is 10% or less of [Selection figure] None |
