HARD DISK DRIVE DEVICE READ-WRITE HEAD WITH DIGITAL AND ANALOG MODES OF OPERATION AND USE THEREOF

摘要

The invention relates generally to hard disk devices, and more particularly, to hard disk devices using read-write components having electromagnetic elements. The invention can be utilized in any application requiring high sensitivity such as ionic particulate flow detection, and weak magnetic planar flux variation and transition detection. The invention combines both Hall Effect sensors and inductive effects to help increase precision of sensitivity, and increase flux noise rejection. Additionally, to acting as a sense element, the invention has the ability to generate a localized electromagnetic flux.
