The effect of pole tip and core saturation of the write head has been observed over a wide range by using a low Curie point ferrite head, of which saturation point varies with its operating temperature. It is shown that the dependence of digital readout signal on write current level is restrained by the head saturation when it occurs in the under saturated or remarkably over saturated region of the medium
