在硬盘驱动器中，离散磁道介质相对于传统的连续介质提供了许多潜在的记录优点。在这项研究中，我们提出了一种新的制造工艺的离散轨道垂直磁介质通过电子束光刻，离子铣削，并使用保护铝牺牲层。介质的物理表征证实了该工艺能够产生图案化轨迹，而不会损坏介质。旋转架分析验证磁盘是可飞行的，能够记录急剧的转变，而不会降低磁信号
Discrete track media offers many potential recording advantages over conventional continuous media in hard disk drives. In this study, we present a novel fabrication process for discrete track perpendicular magnetic media via electron beam lithography, ion milling, and the use of a protective Al sacrificial layer. Physical characterization of the media confirms the process is able to produce patterned tracks with no damage to the media. Spin stand analysis verifies the disks are flyable and capable of recording sharp transitions without any degradation in the magnetic signal
