磁记录中存储密度的增加基本上是通过缩放减小的几何尺寸来实现的，其假设是如果所有尺寸都适当缩放，则记录物理学不会改变。越来越明显的是，现在看到了规模化崩溃的证据。我们将在这里讨论如何打破磁记录的限制设置缩放。特别是，我们将讨论能量辅助记录，畴壁辅助记录，和比特模式的媒体，在记录系统的考虑一些重点。
Gains in storage density in magnetic recording have fundamentally been achieved by scaling—reduced geometrical dimensions under the assumption that the recording physics does not change if all dimensions are scaled appropriately. It is becoming clear that evidence of the breakdown of scaling is now seen. We will here discuss ways to break the constraints on magnetic recording set by scaling. In particular, we will discuss energy-assisted recording, domain-wall-assisted recording, and bit-patterned media, with some emphasis on recording system considerations.
