Co-Ni obliquely evaporated tape and its magnetic and recording characteristics

This paper describes technology for a Co-Ni evaporated tape, a metal evaporated, or ME tape fabricated by a vacuum evaporation method, focusing on magnetic properties, microstructure, recording characteristics and noise prosperties. The high reproduced signal output, low noise and high resolution of ME tape obtained by using a ring head are attributed to oblique anisotropy and a particle-like structure. A breakthrough in improving the durability of ME tape has been achieved by technological improvements in tribology.
