ABSTRACT:
A magnetic recording medium is disclosed which comprises a non-magnetic support and a magnetic layer comprising ferromagnetic powder, provided on the support. The magnetic layer contains silicon and aluminum, wherein the silicon content of ferromagnetic powder is not less than 0.1% by weight, and the ratio by weight of silicon to aluminum is not less than 3, and magnetic layer contains a binder having an anionic functional group.
The magnetic recording medium is excellent in the dispersibility of the ferromagnetic powder of the magnetic layer, and in the balance of magnetic characteristics such as S/N ratio, a squareness ratio, and electromagnetic conversion characteristic, while keeping an excellent running durability.
