Magnetic recording medium |
| abstract |
The present invention relates to a magnetic recording medium comprising: a non-magnetic substrate; a non-magnetic undercoat layer formed on said non-magnetic substrate, said undercoat layer comprising non-magnetic acicular hematite particles containing 0.05 to 50% by weight of aluminum uniformly within the particles, calculated as Al, based on the total weight of the non-magnetic particles and a binder resin,; and a magnetic recording layer formed on said non-magnetic undercoat layer, said magnetic recording layer comprising magnetic particles containing iron as a main ingredient and a binder resin. The magnetic recording medium has small light transmittance, smooth surface, high strength and high durability. |
