Abstract
The effect of interparticle interactions on recording characteristics was investigated by computer simulation on an oblique metal-evaporated tape. It was shown that the magnetic anisotropy derived from the interparticle interactions plays an important role in the minor loop magnetization process and the recording mechanism of the medium. In the present study, the interparticle interactions in metal-evaporated media are considered to come mostly from magneto-static interactions. Computer simulation results based on a medium model that takes account of the magnetic anisotropy derived from the interparticle interactions are quite consistent with the data obtained from experimental measurement. As a result, it is suggested that the magnetic anisotropy originated in magneto-static interactions should be considered in order to understand the recording characteristics of the medium.
