Seagate Scientist Explores Uncharted Realms of Data Storage

Seagate Technology, the world's leading provider of hard disc drives for Internet, business and consumer applications, will present a discussion of future storage technologies at DISKCON Japan 2002. Dr. Ed Murdock, executive director for recording heads Advanced Concepts at Seagate Technology in Minnesota, will discuss potential enabling technologies that can take the industry beyond the 100 Gbit-per-square-inch areal density at the upcoming technical conference.

While recent indications are that the areal density growth curve is slowing from its recent break-neck pace of 150 percent annually, the need for technological innovation is as acute as ever. Putting more information on smaller disc drives is necessary to meet the needs of new markets like Consumer Electronics, and this poses some very difficult challenges in terms of materials, device performance and processing. So what technologies can take us beyond the 100 - 150 Gbit-per-square-inch level? In his talk, Dr. Murdock will address some of the technical challenges driving the need for innovation and Seagate's pioneering work in new realms like perpendicular recording. He will also discuss some of the possibilities for extending head technology to 1 Terabit-per-square-inch or beyond, including Tunneling GMR (TGMR), probe recording and more.

Dr. Murdock earned his Ph.D. in Low Temperature Physics in 1980 at the University of California at Davis. He joined Hewlett-Packard Labs at the end of 1980, where he worked on thin film media development and recording physics and became the Department Manager. He published a number of papers on noise in thin film media and a paper in 1992 on media requirements for achieving 10 Gbits-per-square-inch and beyond. Dr. Murdock joined Seagate in 1992, as senior director for MR Head Development, where he led the development effort on Seagate's first MR head, transferred into production in 1995. He led the Spin Valve development team from its inception in 1995 to the present. Currently, he is responsible for the advanced R&D on technology for recording head transducers, with an emphasis on Perpendicular Recording.

Seagate's ongoing leadership in R&D has enabled the Company to achieve some of the industry's most exciting "firsts"—including the world's first 15,000-rpm disc drive, the highest capacity disc drive at 180 Gbytes, and the fastest PC hard drive. In addition, Seagate drives are among the most reliable and the quietest in the disc drive industry. Seagate's R&D investment in FY2001 was US$862 million, more than that of all other independent disc drive manufacturers combined.

DISKCON Japan is the only tradeshow in Japan dedicated to the Data Storage Industry with exhibitions and technical conferences focusing on new technologies, production issues, and business trends in the data storage industry. The technical conference features some of the world's leading experts in technology and product design, manufacturing solutions, and new product applications and business trends. The conference will be held at Tokyo Big Sight, Tokyo, Japan from 10—12 April 2002.
