The influence of the thickness of a Co-Cr layer in a Co-Cr/Ni-Fe double layer medium on the recording and reproducing characteristics was investigated by computer simulation. In practice, the perpendicular media with a relatively thin Co-Cr layer, about 0.1 μm in thickness, but which is thicker than the longitudinal media, produce high reproduced voltage at high densities. The reason is that the sharp magnetic field distribution of a single-pole-head is created for a thin Co-Cr layer by enhancing the head-to-medium magnetic coupling. As a result, the large residual magnetization remains in the recording process, and the high resolution of the singlg-pole-head generates high voltage in reproduction, even at high densities.
