MAGNETISCHES AUFZEICHNUNGSMATERIAL, DAS IN EINER MAGNETISCHEN AUFZEICHNUNGSSCHICHT METALLOXIDTEILCHEN MIT ADSORBIERTEM RUSS AUFWEIST

摘要

Magnetic recording media are disclosed which comprise a support, and a magnetic recording layer formed at least one side thereof. The recording layer comprises a dispersion, in a binder, of magnetic particles and non-magnetic particles of a metal oxide selected from titanium dioxide, aluminium oxide, chromium (III) oxide and mixtures thereof. Carbon black powder is adsorbed on the metal oxide particles in an amount of from 0.5 to 20 wt % based on the weight of the non-magnetic metal oxide.
