Recording Characteristics of Obliquely Oriented Particulate Tapes.

It has been reported that high-density and widebandwidth characteristics are obtained by using a combination of a ring head and obliquely oriented metal evaporated magnetic recording tapes. Therefore, we developed new equipment for the preparation of obliquely oriented tapes of γ-Fe2O3 particles, and examined themorphology, magnetic properties, and wavelength response of the tapes. The experimental results showed that a tape obliquely oriented at 30°has the highest-output and widest-bandwidth characteristics.
