The recording characteristics of a composite medium with a longitudinal magnetization recording layer as a underlayer of a perpendicular magnetization recording layer were evaluated by using ring-type heads. The results suggest that the residual magnetization mode of the medium is a phase synchronization mode, which forms a horseshoe-shaped magnetization region composed of the strong perpendicular magnetization region of the perpendicular layer and the longitudinal magnetization region of the underlayer. The reproduced voltage of the medium is higher than that obtained by simple superposition of the outputs of the perpendicular top layer and the longitudinal under-layer, and the waveform of the medium shows an almost single-peaked pulse. The recording density response and peak shift characteristics are not restricted by the characteristics of the underlayer. The magnetization state of the medium can be controlled by the medium and head parameters, indicating the importance of optimizing these parameters.
