Recording characteristics of perpendicular recording media with three different stabilizing schemes of soft under (SUL) were investigated; conventional, synthetic antiparallelly (SAP) coupled, and antiferromagnetically (AFM) coupled SULs. The strong

The ability to control head-to-media spacing through a heating element has many technical implications. Properly applying this capability can significantly improve bit error rate (BER) performance in perpendicular magnetic recording (PMR). It also ca

Wide-area erasures of perpendicular head/media at 80 GB/P were investigated. Domain lock up at the writer pole is responsible for both the sector erasure in the down-track direction and the spurious erasure in the cross-track direction. Cross-track e

Previously, we have shown that the transition position shift in a perpendicular recording medium with a recording layer and a soft underlayer (SUL) is one of the major noise sources in high-density recording when abrupt single pole head field is appl
