چکیده

In this paper, we investigate the performance of perpendicular recording channel for dc-full and dcattenuation partial response targets under the environment of electronics noise and jitter noise. We compare the performance of partial-response maximum-likelihood (PRML) and noise-predictive maximum–likelihood (NPML) detector for both types of targets. The NPML system is more suited for dc-attenuation targets, whereas the dc-full targets are suited to PRML system at low jitter noise.

Generalized Partial Response Targets for Perpendicular Recording with Jitter Noise

–In this paper, we propose new generalized partial response (GPR) targets for perpendicular recording whose transition response is modeled as an error function, and compare their performance with the partial response (PR) targets both in the presence and in the absence of jitter noise. Regardless of any jitter noise amount, results indicate that the GPR targets outperform the PR targets, especi...

A Study of Class I Partial Response Signaling for Magnetic Recording

Using a semianalytic technique based on the work of Agazzi and Seshadri, we compare the performance of PR1, PR4, and EPR4 partial response schemes on a magnetic recording channel. The technique includes the effect of imperfect equalization and, in the PR4 case, the effect of employing two interleaved Viterbi detectors. Assuming the Lorentzian channel model and superposition, we use this techniq...
