| titleOfInvention | Magnetic recording medium |
| abstract | A magnetic recording medium includes: a non-magnetic support; and a magnetic layer including a binding agent and a ferromagnetic powder including at least one epsilon-type iron oxide compound selected from the group consisting of ε-Fe 2 O 3 and compound represented by Formula (1) (A represents at least one metal element other than Fe, and a satisfies 0<a<2), in which a value of magnetic field Hc with respect to magnetic field Hc′ is from 0.6 to 1.0, and Hc′ satisfies Expression (II): 119 kA/m<Hc′<2380 kA/m. The magnetic field Hc′ is a magnetic field when the value of Expression (I): d 2 M/dH 2 is zero, wherein a magnetization M, which is obtained by a magnetic field-magnetization curve obtained by measurement under specific conditions, is subjected to second derivative with respect to an applied magnetic field H, and magnetic field Hc is a magnetic field when the magnetization is zero in the curve. n ε-A a Fe 2-a O 3 (1) |
