| 熱寫磁讀記錄媒體及其製作方法 |
本發明提供一種熱寫磁讀之記錄媒體及其製作方法，其係引入一FePt磁性層，利用FePt/CoTb雙層膜結構之間的交換耦合(exchange coupling)現象，而於室溫下產生足夠之磁通量以供訊號讀取。本發明之記錄媒體於室溫下即具有高飽和磁化量與高頑磁力，因而深具超高記錄熱寫磁讀之應用潛力。
A novel heat assisted magnetic recording (HAMR) medium and the fabrication method therefor are provided. The exchange coupling effect occurring at the interface of FePt/CoTb double layers is adopted, and thus the resulting magnetic flux would be sufficient enough to be detected and readout under the room temperature. The provided HAMR medium exhibits a relatively high saturation magnetization and perpendicular coercivity, and thus possesses a great potential for the ultra-high density recording application.
