Abstract:The influence of surface properties on the recording performance of thin films is at best illustrated in the perpendicular recording mode. The roughness and the oxidated/segregated top layer will redistribute the magnetic charges at the surface. The stray field which is so important in the reading process will deteriorate. Attention will be focussed on the relation between the stray field and magnetization (J.J. Miyata et al., IRE Trans. Elect. Comp. (1959) 159) as a function of the above mentioned properties. Using experimental data the reduction of the maximum readable information density is calculated.
