Perpendicular Recording Media Imaging Using Dynamic Read-Back Microscopy

Abstract

Magnetic patterns on perpendicular recording media were imaged by spin-stand level dynamic read-back microscopy. High-density tracks are clearly resolved up to 1000 kfci and details of magnetic bit structure, not usually observable using standard read-write tests, are readily observed. Encroachment of tracks on Co-Cr-Pt-O media with low oxygen content and… (More)
