PMR Head and Media oral history panel

One of the most significant recent technology developments was the commercialization of perpendicular magnetic recording. Starting in 2005 adoption of perpendicular magnetic recording significantly facilitated an eightfold increase of data capacity in hard disk drives. Hard disk drive capacities of up to 10 TB are the norm today. This breakthrough was made possible by use of a unique perpendicular magnetic recording medium, known as the oxide medium, first developed in Toshiba under the leadership of Dr. Yoichiro Tanaka. The oxide medium was adopted by the entire hard disk drive industry. The first generation of this perpendicular magnetic recording disk was manufactured by Showa Denko. It was matched with a first generation perpendicular magnetic recording head supplied by TDK. This oral history records the three-way collaboration between these companies that resulted in Toshiba’s first PMR hard disk drive. The interview will include Messrs. Yoichiro Tanaka from Toshiba, Hiroshi Sakai from Showa and Koichi Terunuma from TDK
