Tu was co-founder & chairman of Komag from 1983 until his retirement in early
2000. In 1984 Komag was one of the first OEMs to ship a carbon overcoated sputtered magnetic medium disk to the HDD industry.
He started his career at IBM, Endicott, then Northrop, Los Angeles andn 1971 he joined Xerox PARC to work on the development of various magnetic recording materials. Tu was born in Taiwan and came to United States in 1961 to attend the University of Minnesota, where he obtained his PhD in materials science & engineering. See, My Personal Experiences In Founding Komag Inc. |
Tom was CTO of Komag Inc. prior to $1.2B purchase by Western Digital in 2007. Developed many of the key components of hard disk media produced by Komag Inc. Holder of 24 issued patents on hard disk media technology. Over 50 technical publications, numerous invited talks at conferences and at universities. Expertise in magnetic thin film technology, deposition methods, hard overcoat and tribology. | Len founded Grenex in 1982,
one of the early thin film media suppliers; it was acquired by and became Seagate Magnetics.
He has almost 40 years experience in sputtering and plating metal films in the hard disk drive and other industries, including positions at Dastek and International Memories Corp. He is the inventor of the WAffle head, has patents on combining sputtering and electroless nickel plating and has organized several HDD symposia. Len was awarded a Doctor of Engineering Science, Extractive Metallurgy, from Columbia University. |
At Seagate for 19 years as Executive Director of Product Development Engineering and Advanced R&D and in other positions Ed led the development and integration engineering into new products of various cutting-edge technologies such as TMR & GMR heads and perpendicular recording. While at HP (12 years) he lead teams that developed a variety of thin film magnetic media, Dual Stripe Magnetoresistive (DSMR) heads and innovative tribological solutions. In 1985 HP shipped one of the first production HDDs incorporating sputtered magnetic media with a carbon overcoat. Ed has 16 patents and received his PhD in Physics from UC Davis. | Tadashi is an HDD data storage technologist who started his career in IBM Research. In 1984 at Almaden he engaged in early development of Thin Film Disks, focusing on understanding the relationship between the sputter process, film microstructure and recording performance. This was a key component of IBM's 1989 demonstration of 1 Gb/in2 areal density. He then coordinated the introduction of thin film disks into eleven HDD products in IBM, Fujisawa. Subsequently he has held senior technology management positions at Maxtor and Hitachi. He has a Ph.D. in Applied Physics from the California Institute of Technology. |
