摘要

在硬盘驱动器(hdd)中，在制造过程中需要预先校准多个磁头之间的磁头倾斜误差。由于环境变化或非操作冲击，额外的头部歪斜误差跨行程可能导致。本文提出了一种可靠的伺服启动时直流磁头偏斜误差的再校准策略，并提出了一种扇形相关的磁头切换方案以避免错误校准。试验结果表明，该方法能有效提高非操作冲击后的驱动性能。

Reliable recalibration of DC head skew in hard disk drives

In hard disk drives (HDDs), head skew error among multiple heads is pre-calibrated during manufacturing process. Due to environmental change or non-operating shock, additional head skew errors across stroke may be resulted in. In this paper, a reliable recalibration strategy of DC head skew error during servo startup is proposed, where a sector-dependent head-switching scheme for avoidance of wrong calibration is developed. Test results demonstrate its effectiveness to enhance drive performance post non-operating shock.
