Performance comparison of post-processor for PRML channel in perpendicular magnetic recording
Source abstract
Abstract
Abstract In this paper, post-processors for the partial-response maximum-likelihood (PRML) channel combined with the Reed–Solomon (RS) encoder/decoder are studied in perpendicular magnetic recording. The bit error rate (BER) performance is obtained by read/write experiments using a spin-stand with a perpendicular medium and single-pole-type/giant magnetoresistive (SPT/GMR) head. The experimental results show that post-processors improve linear densities of about 10–20 kBPI in perpendicular magnetic recording.
