Ferromagnetic powder, and coating material and magnetic recording medium using same |
| abstract |
A magnetic powder is provided composed of particles having a balanced shape and distribution, the particles having a small, uniform volume, making it possible to achieve improved density and reliability of a coating type magnetic recording medium. The magnetic powder has Fe as a main component, and is comprised of particles having a cross-section perpendicular to the particle major axis that is substantially round or elliptical, wherein a standard geometrical deviation indicating the variation in cross-sectional area thereof is within the range of 1.01 to 3.0. The invention is also directed to a magnetic powder in which the standard geometrical deviation indicating the variation in the particle volume is within the range of 1.01 to 4.0, and the standard geometrical deviation indicating variation in the flat acicularity is within 1.01 to 2.0. |
