A Post-Compensation Scheme for Peak-Detect Channel

Abstract

A post-compensation procedure for peak detection in disk-drive systems has been tested using a software channel on (2, 7) RLL codes. It uses a table look-up method to determine the detection window boundaries for the center pulse in every three-pulse sequence. Preliminary test results against readback equalization schemes suggest that the procedure may perform better than equalization techniques in terms of the ability to reduce the soft error-rate. © 1990 IEEE
