Recording study of percolated perpendicular media

Abstract

We examine the magnetic recording properties of percolated perpendicular media (PPM) fabricated by depositing a Co/Pt multilayer film on top of nanoperforated templates created by self-assembly. We characterize the recording performance by examining the magnetic transition jitter in patterns written to the media using a hard disk drive write head. The transition jitter is lowest in the media created using the template with the highest perforation density, which demonstrates a route for further improving PPM-based recording media.
