• Metal evaporated(ME) tapes have an easy axis of magnetization tilted about 20∼30 degrees out of the film plane. Recording characteristics depend on the easy axis of magnetization and magnetic field of the head. We have been investigated recording characteristics of ME tapes by using a computer simulation. Recording simulations were performed for the media having various easy magnetization direction such as 0deg∼90deg. We have been also investigated the relationship between easy magnetization direction of media and reproduced output at short recording wavelengths by using an symmetric and asymmetric saturation magnetic flux density(Bs) Metal In Gap(MIG) heads. We found that an asymmetric head with a higher Bs at the leading edge is effective on high reproduced output of both high angle and perpendicular easy axis media. especially at short wavelengths.
