We investigated the magnetic and perpendicular recording properties of DC magnetron sputtered Co/Pt multilayer media using a single pole contact head. Thin Co/Pt multilayer films have attractive magnetic properties for perpendicular recording. This medium shows excellent recording performances relative to CoCrTa conventional media. The multilayer films sputtered at high Ar pressure have columnar microstructure. This structure contributes to large coercivities and low media noise. This paper shows the possibilities of ultra-high-density recording using combination of thin film metal multilayer media and inductive single pole head.
