摘要

随着密度每年增加100%，接近超顺磁极限，在硬盘驱动器的读通道中需要更强的误差控制系统。提出了一种校正由高彩色噪声引起的长误差的技术，这种高彩色噪声是现代磁头和介质的典型特征。我们介绍了一种基于硬件系统的非常高速率的代码结构，用于纠正给定列表中的错误，并演示了将这些代码用于结合错误事件检测和列表软解码的方案时，可以获得可观的信噪比增益。

Error-event detection codes for partial response channels

With an annual increase in density of 100% approaching superparamagnetic limits much stronger error control systems are required in read channels for hard drives. A technique is presented for correcting long errors that are the result of highly colored noise typical for modern magnetic heads and media. We introduce a sofic system-based construction of very high rate codes for correcting errors from a given list, and demonstrate a substantial SNR gain when these codes are used in a scheme that combines the error event detection and the list soft decoding.
