Abstract:
Magnetic recording tape is suitable for data recording mechanisms equipped with brass or other soft heads when its magnetizable layer is based on ferromagnetic iron oxide particles and contains titanium dioxide or other soft head cleaning agent which has a hardness approximating or slightly exceeding that of the iron oxide. The magnetizable layer preferably is free from, but may also contain unusually small amounts of hard head cleaning agent such as alumina.
