    Abstract
    Get ready for a wild ride starting with the vast distances of outer space and ending with the tiny distances that separate atoms. For a very different perspective on data storage, each slide in the presentation looks at things on a scale that is a factor of ten smaller than the previous slide. The common thread is the technology of information storage. Information storage is what defines human history and it is the machine-readable data storage developed in the last half-century that provides the foundation of the modern information age. More than anything, data storage implies magnetic recording and the hard disk drive. The humble Hard Disk Drive contains such exquisite technologies and operates at such astounding precision that it almost defies belief. Yet, our industry churns out these devices by the hundreds of millions and sells them for a few tens of dollars each. Please enjoy this light-hearted logarithmic romp through storage technology from interstellar space to interatomic spacings.


    Biography
    Dr. Roger Wood hails originally from the UK and holds degrees from London University and the University of British Columbia. He is currently a Fellow with Western Digital in San Jose, California. Dr. Wood has a long history in the Magnetic Recording industry starting at Ampex in 1979, moving to IBM in 1986, to Hitachi in 2003, and to Western Digital in 2012. In 1996, he enjoyed a year at the Data Storage Institute, Singapore. In 2003-2004, he was fortunate to take an assignment in Odawara, Japan. At Ampex, Dr. Wood was the inspiration behind the introduction of the first PRML channel. At Hitachi, he led the advanced development effort on perpendicular recording. Dr. Wood is perhaps best known for predicting that conventional magnetic recording would be limited to about 1 Tbit/in2. To extend magnetic recording on conventional granular media, he proposed `TDMR?, an approach now being actively pursued by industry. Dr. Wood's interests include magnetism, magnetic recording, signal-processing, and mechanical dynamics. He holds 27 US patents and is an author on over 90 journal papers. Dr. Wood is an IEEE Fellow and was the recipient of the 2009 Magnetics Society Achievement Award.)
