                The $100-billion data-storage market is driven by, arguably, the fastest moving technology in high-tech industry, where the nano-scale is commonplace in products.  Not only are bits measured in nanometers, but data rates (> GHz) have driven timescales sub nanosecond.  Over the last decade, in particular, there has been unprecedented acceleration in the development of advanced magnetic recording technologies, from perpendicular to Heat, Microwave and Electrically assisted magnetic recording (HAMR, MAMR and EAMR).  Along the way, there have been numerous physical barriers overcome, while even more daunting tasks lie ahead.  For the magnetics that underpin hard disk drives, in particular, there are many physical barriers we need to overcome as we reduce bit dimensions and increase data rates with each generation of the technology.  For example, smaller bits are more susceptible to thermal agitation, while data rates are limited by the relaxation rates of magnetic excitations.  In this talk, I explore the physics and engineering of shrinking bits and short timescales.

 

Speaker Biography

Tom Clinton holds a doctorate in Physics from the University of Maryland, where his thesis was on magnetic properties of superconductors.  He has worked in the data-storage industry since 1999, spending a decade at Seagate Technology's research division in Pittsburgh, PA, and is currently a member of the research staff at Hitachi's San Jose Research Center.  At Hitachi, he works on advanced storage technology, FIB/SEM applications, and fabrication and characterization of magnetic and optical devices.
