Abstract

In a double layered perpendicular magnetic recording medium, recording resolution and time decay of output signal have been studied. Introduction of a Stacked intermediate layer (NiFeNb/Ti) between a soft magnetic back layer and a storage layer improves magnetic property of the storage layer. The stacked intermediate layer can reduce the initial growth layer of the storage layer by hetero-epitaxial growth. Time decay of output signal for a medium with the stacked intermediate layer was suppressed within -0.4 dB at 1000 seconds after recording at 100 kFRPI. A reproduced signal at an extremely high linear density of 950 kFRPI has been confirmed by a CF-SPT head for writing and a GMR head with track width of 0.4 micrometer for reading.
