Seagate Breaks World Magnetic Recording Density Record - 421 Gbits Per Square Inch Equivalent to Storing 4,000 Hours of Digital Video on Your PC

Achievement Underscores Strong Advancement and Future for Hard Disc Drive

    SCOTTS VALLEY, Calif., Sept. 15 /PRNewswire-FirstCall/ -- Seagate
 Technology (NYSE:   STX) today announced the results of a magnetic recording
 demonstration, setting a world record of 421 Gbits per square inch (421
 Gbit/in2). The demonstration used perpendicular recording heads and media
 created with currently available production equipment that validates
 Seagate's ability to scale the technology for the foreseeable future
 without major technology changes or capital additions. Dr. Mark Kryder of
 Seagate unveiled the findings during his keynote presentation at the IDEMA
 DISKCON show in celebration of the 50th anniversary of the hard drive.
     The demonstration is evidence of the continued momentum in disc drive
 innovation, and reaffirms the disc drive as the undisputed king of storage
 when capacity and cost-effectiveness are both required. At the demonstrated
 density level, Seagate expects the capacity ranges to result in solutions
 ranging in 40GB to 275GB for 1-and 1.8-inch consumer electronics drives,
 500GB for 2.5-inch notebook drives, and nearly 2.5TB for 3.5-inch desktop
 and enterprise class drives. At 2.5TB capacity, a hard drive would be
 capable of storing 41,650 hours of music, 800,000 digital photographs,
 4,000 hours of digital video or 1,250 video games. Seagate anticipates that
 solutions at these density levels could begin to emerge in 2009.
     "Today's demonstration, combined with recent technology announcements
 from fellow hard drive companies, clearly shows that the future of hard
 drives is stronger than ever," said Bill Watkins, CEO of Seagate.
 "Breakthroughs in areal density are enabling the digital revolution and
 clearly indicate that hard drives can sustain their advantage to meet the
 world's insatiable demand for storage across a wide range of market
     The Future Ahead from the World's #1 Disc Drive Manufacturer
     Seagate's leadership in R&D and manufacturing has enabled the Company
 to consistently deliver its award-winning products first to the market. As
 the company with the broadest range of products using perpendicular
 recording, no other company is better positioned to serve the storage needs
 of the future than Seagate.
     Seagate continues to invest its resources in research to serve the
 needs of the storage market and sees a strong future in disc drive
 development. During Dr. Kryder's DISKCON keynote, he explained future
 technologies designed to extend magnetic recording beyond perpendicular
 including Heat Assisted Magnetic Recording (HAMR) and bit patterned media
 techniques. Using these recording methods, Seagate researchers have
 estimated capacities to reach or exceed 50 terabits per square inch.
     Demonstration Technical Details
     The areal density of 421 Gbpsi was demonstrated using 10 E-3 off-track
 bit error rate criteria with 5% squeeze and meeting a 10% off-track
 capability at a data rate of 735 megabits per second. The track density was
 275,000 tracks per inch, and the linear density was 1.53 million bits per
 inch for a bit aspect ratio of 5.6. The demonstration was conducted using a
 product channel, perpendicular head, and thermally stable media created
 with current production equipment.
