大规模的数据增长正在加速对存储的需求。硬盘驱动器读/写技术不断发展以支持这一需求。这份高级存储研究联盟报告结合了自上而下（系统）和自下而上（微磁）的方法，定义了每平方英寸2.4、4.0和6.0兆比特（Tbpsi）的读取器技术路线图，包括尺寸和性能目标。我们研究了分辨率、SNR、稳定性和制造要求、挑战和差距。我们表明，今天的自旋阀为基础的阅读器设计的扩展可能使4 Tbpsi，但必须关闭显着的差距。对于更高的面密度，我们回顾了未来的读卡器设计，挑战，并讨论了潜在的解决方案路径。
Massive data growth is accelerating the need for storage. Hard disk drive read/write technology continues to advance to support this demand. This Advanced Storage Research Consortium report combines a top-down (system) and bottom-up (micromagnetic) approach to define a reader technology roadmap for 2.4, 4.0, and 6.0 terabits per square inch (Tbpsi) including dimensional and performance targets. We examine the resolution, SNR, stability and manufacturing requirements, challenges, and gaps. We show that the extension of today's spin valve-based reader designs may enable 4 Tbpsi, but significant gaps must be closed. For higher areal densities, we review future reader designs, challenges, and discuss potential solution paths.
