Method to stress relieve a magnetic recording head transducer utilizing ultrasonic cavitation

Magnetic heads are fabricated by slicing and dicing wafers into row bars, which undergo frontside lapping and backside lapping. These lapping processes, as well as other processes, induce stresses on the row bars that are released prior to finalizing the magnetic head. Ultrasonic impact technology i...
