长期以来，人们一直在研究将离散轨道图案化到磁盘上以用于磁数据存储的潜在好处。一种用于制造具有成本效益的离散轨道记录(DTR)介质的实用方法阻止了这种盘被引入产品中。在本文中，将描述一种利用纳米压印光刻技术在盘基板表面上创建平台和沟槽结构的工艺。讨论了该结构的几何形状以及磁头的磁写和读宽度的设计考虑。还给出了显示DTR介质的磁特性和记录性能的数据。
The potential benefits of patterning discrete tracks onto a disk for magnetic data storage have long been investigated. A practical process for manufacturing a cost-effective discrete track recording (DTR) medium has prevented such a disk from being introduced into a product. In this paper, a process utilizing nano-imprint lithography techniques to create a land and groove structure on the surface of a disk substrate will be described. Design considerations for the geometry of the structure, as well as of the magnetic write and read widths of the head, are discussed. Data showing the magnetic characteristics and recording performance of a DTR medium are also presented.
