Abstract

This work investigates various types of reader designs as applied to magnetic recording. Reciprocity principle is used to study playback response. It is shown that both shielded and not shielded differential readers exhibit magnetic playback properties advantageous for achieving extremely high areal bit densities. Modified design of differential readers with one MR sensor is proposed to overcome the manufacturability issues associated with a conventional double-MR sensor differential reader.
