概要
- 論文の詳細を見る
TbFeCo perpendicular magnetic recording media were developed by employing a NiP underlayer to control the magnetic properties of TbFeCo magnetic layer.With the NiP underlayer the magnetization reversal changed from the wall motion to the rotation mode.Dynamic write-read characteristics of a single-layer medium were examined using a conventional merge-type GMR head with a write core width of 1 μm that was designed for longitudinal magnetic recording.A clear magnetic pattern of 450 kFCI, high media SNR and acceptable overwrite properties were obtained.It was shown the thermal stability of the TbFeCo medium is good enough for practical applications.A double-layer medium with a soft-magnetic backlayer exhibited a practical overwritability for a narrow track pitch of 0.4μm.
