| titleOfInvention |
Magnetic recording medium containing ferromagnetic metal powder and a specific fatty acid ester in a content dependent upon the specific surface area of the ferromagnetic metal powder |
| abstract |
A magnetic recording medium having on a non-magnetic support a magnetic layer mainly composed of a ferromagnetic metal powder and a binder resin is disclosed, wherein the specific surface area S (m2/g) of the ferromagnetic metal powder is from 30 to 65 and the magnetic layer further contains a fatty acid ester in a content Y (% by weight) to the ferromagnetic metal powder of the range of 0.05S+5.5</=Y</=-0.2S+24 when the specific surface area S is from 30 to less than 50 and the range of 0.06S+4.7</=Y</=-0.13S+21 when the specific surface area S is from 50 to 65. The magnetic recording medium is suitable for high density recording and exhibits excellent running durability. |
