Abstract

Effects of saturation flux density (Bs) of read/write head on the recording characteristics of perpendicular/longitudinal composite medium were investigated. It was found that the recording sensitivity was improved by applying the higher Bs head. In higher density region, the reproduced-voltage-enhancement was enlarged with high Bs head, however, at the higher MMF region, the read/write characteristics was worse because the head field penetration becomes broad. Therefore, it was necessary to optimize the medium parameters in account to the head parameter.
