已经展示了通过利用双磁体母版（DMM）介质在能量辅助磁记录（EAMR）介质上的磁性印刷。DMM介质通过用由高磁性和低磁性磁体组成的两种不同的磁性图案增强记录场来有效地改善打印特性。通过微磁学模拟，研究了磁性印刷在EAMR介质上的磁化强度分布和印刷性能。DMM可以在EAMR介质上清晰地打印L/S和棋盘图案，并且DMM PP上级传统的主介质。DMM打印机可以将伺服信号写入EAMR介质，其重复性高达30 kOe。EAMR介质中较窄的晶粒切换分布增强了打印特性。利用DMM介质的磁性打印的潜力被揭示为将伺服信号写入到EAMR介质上。
The magnetic printing onto energy-assisted magnetic recording (EAMR) media by utilizing double magnet master (DMM) media has been demonstrated. The DMM media is effective for improving printing characteristics by enhancing recording field with two different magnetic patterns that consist of high coercivity and low coercivity magnets. The magnetization distributions and printing performances (PPs) for magnetic printing onto EAMR media were evaluated by the micromagnetic simulation. The DMM can clearly print the L/S and checkerboard patterns onto EAMR media, and the DMM PP was superior to that of the conventional master media. The DMM printing could write the servo-signals onto the EAMR media with the coercivity of up to 30 kOe. The narrower switching distributions of grains in EAMR media enhances the printing characteristics. The potential of magnetic printing with DMM media was revealed for writing the servo-signals onto the EAMR media.
