Noise from the underlayer is observed with a Mn-Zn ferrite head and a Co-Mo-Zr low coercivity amorphous underlayer. Three kinds of noise are observed, spike noise (s), medium noise (m), and low noise (l). s noise is generated through the domain walls of an underlayer. m noise originates from the interaction between an underlayer and the reproducing head's residual magnetization. Three effective methods are tested for reducing the noise: (1) increase of coercivity of an underlayer, (2) use of an ac-erased head, and (3) use of a thin-film head.
