Description
This oral history records the contributions of Drs. Dieny, Gurney, Mustafa Pinarbasi and Virgil Speriosu to the invention, development and commercialization of the magnetic recording head based on the giant magnetoresistance (GMR) phenomenon discovered by Fert and Grunberg. The invention of the GMR head is especially noteworthy because it enabled the second generation of magnetoresitive heads which were used to read data in hard disk drives between 1997 and 2006. Starting in 2005 key GMR head-related innovations enabled the commercialization of the tunneling magnetic junction devices used in tunnel magnetoresistive (TMR) heads and magnetic random-access memories (MRAM). All modern disk drives and tape drives use TMR heads to read data.
