Abstract :
Noise reduction in double-layered perpendicular recording media with a thick soft magnetic backlayer was studied. Although the medium noise was increased with the backlayer, the noise for quaternary alloy films could be substantially reduced by introducing a certain intermediate layer between the alloy layer and the backlayer. The double-layered medium obtained exhibited a waveform with sharp transitions as well as a low noise property when recorded with a single pole head. The recording performances suggested the potential of the medium for a high areal density recording around 50 Gbit/in2
