Monday, December 14, 2009, 10:00 am — NSLS-II Seminar Room, Bldg. 817
This talk will investigate the transition of Anisotropic Magneto-Resistance (AMR) to Giant Magneto-Resistance (GMR) in tape drives. Although GMR was introduced in the late 90’s in disk drives, tape drives are just beginning to implement this technology. To provide a context for this seemingly late adoption, an introduction of magnetic recording head fundamentals will be given followed by scaling issues that has governed the magnetic data storage industry. These scaling issues provide the motivation for the transition from AMR to GMR in tape drives as well as the transition to Tunneling Magneto-Resistance (TMR) in disk drives.
