Constrained Coding for Magnetization Transition Noise of Ultra-High Density Magnetic Storage 增强出版
摘要
随着磁存储记录密度的提高，记录位间距减小，磁化跃迁噪声显著提高，由此极大地影响回读信号质量.为了降低超高密度磁存储系统记录图案磁化跃迁噪声的干扰，本文分析研究了磁化跃迁噪声对回读信号质量的影响，提出了限制连续跃迁的最大跃迁游程长度受限（Maximum Transition Run，MTR）约束编码MTR（
j
=1），与允许连续跃迁的约束编码MTR（
j
=2）和MTR（
j
=3）相比，可有效抑制磁化跃迁噪声.通过实验测试了回读信号的检测效果，当信噪比为12 dB时，与MTR（
j
=2）、MTR（
j
=3）相比，MTR（
j
=1）相对误码率
分别降低了约30%和60%，证实了限制连续跃迁约束编码MTR（
j
=1）的数据检测可靠性更高.
Abstract
As the recording density of magnetic storage increases
the recording bit spacing decreases and the magnetization transition noise increases significantly
which greatly affects the quality of the readback signal. To mitigate the interference of magnetization transition noise problem among recording patterns in ultra-high density magnetic storage systems
the maximum transition run (MTR) constraint code MTR(

)
which limits the continuous transition
is proposed to effectively suppress the magnetization transition noise compared with the constraint codes MTR(

https://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=80635012&type=

) and MTR(

which allow continuous transitions. We investigate the detection effect of the readback signal experimentally. When the signal-to-noise ratio is 12 dB
the detection bit error rate (BER) of MTR(

https://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=80635010&type=

) is reduced by about 30% and 60% relatively compared with MTR(

https://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=80635021&type=

respectively. We confirmed that the MTR(

) constrained coding that forbids continuous transitions can achieve higher data detection reliability.
