摘要：

Barium ferrite particulate media have been applied to recording tapes for a high-band 8mm VCR, with full compatibility with metal particulate tapes, although they have remarkably different magnetic and recording characteristics. The compatibility of barium ferrite tapes to metal particulate tapes has been attained by adopting barium ferrite particles with an average diameter of 50 nm and a diameter to thickness ratio of 3.5. orientating the particles longitudinally, and adjusting coercivity to about 1300 Oe. which is about 200 Oe lower than the coercivity of metal particulate tapes.
