Jim Bain

Carnegie Mellon University
Electrical and Computer Engineering
Ph.D., Materials Science and Engineering, Stanford University, 1993

James "Jim" Bain holds a B.S., a M.S., and a Ph.D. in Materials Science and Engineering. He received his first degree from the University of Pennsylvania and the other two from Stanford University. Following his graduation in 1993, he joined CMU, where he is now a professor of Electrical and Computer Engineering. He also holds a courtesy appointment in the Department of Materials Science and Engineering and is associate director of the Data Storage Systems Center (DSSC). He is a member of the Materials Research Society and the IEEE Magnetics, IEEE Electron Devices, and IEEE Photonics Societies.


Information Storage Systems Physics
As Associate Director of the Data Storage Systems Center at Carnegie Mellon, Professor Bain is interested in storage systems architectures and performance specifications, as they set the requirements for storage devices. Specifically, he is interested in how systems specifications set the performance requirements for recording heads - the transducers that must deliver energy to the recording medium and thus change its state in a reproducible way. Within this context Prof Bain has been an avid participant in roadmapping and workshops on magnetic disk technology, magnetic tape technology, optical disk technology and probe storage technology.
Thin Films and Devices for Information Storage Systems
Within information storage systems like hard disk drives, tape drives, etc., there are core technologies in thin film materials and devices that are used to fabricate heads and media. Prof Bain has an active research program in the fabrication of and characterization of these materials and devices. Specific examples of recent areas of activity are:
Thin film FeCo alloys for high magnetization write poles
Magnetic pole dynamics in high speed write heads
Very small aperture lasers for near field optical and heat assisted magnetic recording
Field emission assisted magnetic probe recording
Nanostructured magnetic disk media using self-organized nanomasks
Sputtered thin film media for tape using CoCrPt/SiO2 composite media
Cr-SrZrO3 materials for resistance switching applications
