Biography:Hardayal "Harry" Singh Gill
Hardayal “Harry” Singh Gill (born 1952 in Amritsar, Punjab, India ) is an American electrical engineer. Gill has made notable contributions to the magnetoresistive recording heads. He has been associated with various IT organizations including Hewlett-Packard and IBM where he developed and integrated their technological infrastructure.[1][2][3]
Education
Gill completed his Bachelor of Science degree from Punjab University in Patiala, India, in 1971 and a master's degree from the same university in 1973. He moved to the US in 1974, where he enrolled in the University of Minnesota in Minneapolis to complete his Doctorate of Philosophy (PhD) in 1978.[1][4]
Career
Gill began his professional career with the National Semiconductor Corporation in Santa Clara, California, in 1978. He worked as a design engineer on Magnetic Bubble Memory Group. He then switched to Hewlett Packard Labs in Palo Alto, California. He was an active member of the technical staff there in 1985, and then performed duties as a project manager till 1990. During his tenure, his major research work was based on thin-film and Magnetoresistive (MR) Heads.[1]
He joined IBM Corporation in San Jose, California where he worked as an IBM Distinguished Engineer. His major research at IBM was focused magnetic recording heads. He later continued working for Hitachi Global Storage Technologies from 2002 to 2012 as a Distinguished Engineer. He then got acquainted with Western Digital Corporation till 2016, where his role was that of a technologist centered on magnetic recording heads development.[3]
Accomplishments
Gill has over 320 US patents for his contributions and research on memory and recording components. The present research earned him to be nominated as a Fellow of Institute of Electronics and Electrical Engineering (IEEE) in 1995. He has also featured as an electrical engineer in Marquis Who's Who.[1][5]
He was also involved in the research and development of the first application of MR heads to HDD at the IBM Corporation. The research project earned him an IEEE Fellowship offer. After that he designed and developed the industry's first-ever GMR heads which were inaugurated in 1997 at IBM. Due to his contribution, the organization named him IBM's Distinguished Engineer in the same year. Gill was among the first engineers to understand the concept of thin anti ferromagnetic materials and negative delta M applied on GMR as well as the fact that MTJ heads can help in achieving self-pinned designs. He has also designed and constructed the highest capacity bubble memory chips worth 4M bit, with the National Semiconductor Corporation's design group in 1980.[6][7]
A major chunk of his patents consists of research work on magnetic thin film device designs, consisting of MR, GMR, MTJ-based sensor, Spin Valve Transistor, CPP GMR and memory chip design. He also developed magnetic thin films and measurement tools for implementing testing procedures, to ensure high-quality performance and reliability. He also executed performance optimization practices by modeling and measurement. He has also developed system-level testing and characterization practices to develop device properties to enhance the overall system performance. [3][8]
