This paper reports on the recent breakthrough of achieving high orientation ratio (OR) on directly textured glass substrates. We present a unique medium design combining seedlayer, underlayer, and an antiferromagnetically coupled (AFC) magnetic layer structure. Such a structure gives rise to a high OR and leads to significant improvement of recording performance. This technology has enabled the extension of glass disk media to ultra-high density longitudinal recording.
