Abstract

Media with excellent signal to noise properties and adequate high temperature thermal stability have been developed for over 20 Gbit/in(2) recording. The media are fabricated by de magnetron sputtering onto textured NiP films on AI-Mg substrates, The magnetic layer is a CoCr-based quaternary alloy with (11.0) preferred orientation on a Cr alloy (002) underlayer, The average grain diameter has been reduced to an average of < 10 nm, TEM-EDX studies revealed that Cr segregation has been enhanced compared to a previous CoCrPtTa media used for 15 Gbit/in(2) recording resulting in improved Co to Crcore composition and increased grain boundary Cr content. Spinstand measurements of the thermal decay after annealing at 65 degrees C indicate sufficient thermal stability at 400 kfci for media with Mr delta > 0.3 memu/cm(2)consistent with magnetometry measurements.
