A New Thermal Asperity Detection and Correction Algorithm for Perpendicular Recording Channels

Abstract

The thermal asperity (TA) defect resulting from the collision between an asperity and the magneto-resistive (MR) read head can distort the readback signal to the extent of causing possible sector read failure. This paper presents a new TA detection and correction algorithm for perpendicular recording channels. The proposed algorithm consists of two channels… (More)
