Abstract

The storage density of conventional thin film recording media, where each bit is comprised of several hundred grains, is limited by superparmagnetism, since thermal excitation of the magnetization may degrade recorded information. Patterned magnetic media where magnetic bits are recorded on pre-defined, single-domain islands is one of the proposed approaches for extending magnetic storage densities beyond the limit set by thermal decay for conventional media. In this paper we discuss writing and reading from single domain magnetic islands with a conventional recording head, compare the performance to unpatterned media, and present a possible manufacturable approach to achieving run-scale patterning over disk sized areas.
图案介质上的磁记录
传统的薄膜记录介质的存储密度受到超磁的限制,因为每个比特由几百个颗粒组成,因为磁化的热激发可能会降低记录的信息。将磁位记录在预先定义的单畴孤岛上的图案磁介质是将磁存储密度扩展到传统介质的热衰减限制之外的一种建议方法。在本文中,我们讨论了用传统的记录磁头从单域磁岛写入和读取,将其性能与非图像化介质进行比较,并提出了一种可能的可制造方法来实现磁盘大小区域的运行规模图像化。
