摘要
A perpendicular magnetic recording media with a patterned soft magnetic underlayer is disclosed. The recording media may be a disk including a substrate, a patterned underlayer, and a magnetically hard recording layer. The underlayer may be provided in the form of concentric bands having widths less than the track widths of the recording layer. The patterned underlayer reduces or eliminates adjacent track interference.
