摘要：
An apparatus and system for reducing noise detected by a magnetic read head. In particular it relates to reducing magnetic interference at a magnetic read head by dynamically positioning a piece of highly permeable nickel-copper alloy near the magnetic read head thereby shunting the interfering magnetic radiation away from the read head.
