METHOD OF MANUFACTURING MAGNETIC PARTICLES |
| 摘要 |
The method of manufacturing magnetic particles, wherein the magnetic particles are magnetic particles for magnetic recording, and includes subjecting starting material magnetic particles to glass component-adhering treatment to be adhered with a glass component, and subjecting the magnetic particles after the glass component-adhering treatment to coercive force-reducing treatment with heating, to provide magnetic particles having lower coercive force than the starting material magnetic particles. |
