Magnetic recording medium

摘要

Disclosed is a magnetic recording medium comprising a nonmagnetic support, a lower nonmagnetic layer and an upper magnetic layer. The lower nonmagnetic layer is coated on the support, comprises an inorganic nonmagnetic powder dispersed in a binder, and is surface-coated with an inorganic oxide. The upper magnetic layer has a dry thickness of 1.0 micrometers or less and comprises a dispersion of a ferromagnetic powder in a binder. The upper magnetic layer is coated onto the lower nonmagnetic layer.
