Abstract
The lower inductance of Planar Silicon Heads (PSH), the output with no undershoot, the low induced noise due to the common mode coil and the P1 equal to P2 with high accuracy make PSH under the same recording conditions of superior performance compared to Thin Film Heads (TFH). In PSH, the uniaxial permeability is parallel to the disc, in contrast to TFH where the high permeability is perpendicular to the disc. This magnetic difference can explain why PSH exhibit smaller PW50. These points will be discussed in this paper
