Magnetic iron oxide pigment and recording media |
| abstract |
An improved magnetic particulate pigment suitable for use in recording media and media employing it are disclosed. The particles of the pigment comprise a magnetic core with an epitaxial layer containing approximately 0.05-2.0% of the total pigment as zinc ion. A process for preparing such particles is also disclosed. |
