US 9,431,032 B1 · Electrical connection arrangement for a multiple sensor array usable in two-dimensional magnetic recording

Abstract

A method and system provide a magnetic transducer including first and second read sensors, a shield and a conductive via. The shield is between the first and second read sensors. The magnetic transducer also includes first and second read shields. The shield has a top surface and a bottom surface opposite to the top surface. The bottom surface faces the first read sensor. The conductive via is isolated from the first read shield and the second read shield. The conductive via provides electrical contact to the shield and is electrically connected to the bottom surface of the shield.
