New configurations of a thin-film head with 20 tracks per 1/4 inch are proposed. The write head has a groove structure formed into the magnetic substrate to obtain good flux efficiency in the magnetic thin-film effectively to reduce the signal write current. Measured and calculated characteristics are given for this thin-film write head. A high performance magneto-resistive (MR) read head with narrow track width is achieve. The MR elements are required proper preparations to succeed in a simple common biasing configuration. These thin-film heads can realize extremely reliable PCM audio recorders.
