  • Abstract
    The perpendicular magnetic recording/reproduction characteristics of a perpendicular recording thin film head were compared with those of ring heads, in tests using Co-Cr/Co-Zr-Mo double-layer thin film media. The main pole of the thin film head was a 0.3 ¿m Fe-Si-Ru/Ni-Fe multilayered film. The reproduced output per unit coil turn E1k and the overwrite characteristics were both better for the thin film head, and noise levels were lower. These differences were attributed to the larger magnetomotive force coefficients of the medium recording field for the thin film head.
