• A “Paradigm Shift” in tape drive design is A “Paradigm Shift” in tape drive design is needed to achieve 1TB by 2006needed to achieve 1TB by 2006
• Needed to maintain parity with HDD trends Needed to maintain parity with HDD trends
• Solution…Leverage AIT Recording DensitySolution…Leverage AIT Recording Density
• If media were longer and wider (eg. 1/2” at 600m) If media were longer and wider (eg. 1/2” at 600m) then about 5X capacity could be achievable at then about 5X capacity could be achievable at constant areal densityconstant areal density
