摘要: A data storage system comprises magnetoresistive (MR) sensing elements for from a recording medium that is referenced to ground, and an amplifier circuit including biasing stage, amplifying matching each common supply voltage source ground. The stage includes reference current selectively MR element with constant and, in so doing, developing single-ended signal having first dc component. converts the into amplified output second component but which eliminated. creates bias imposes said on converting differential
