1 Magnetic Tape: Technology Dr. Richard H. Dee

2 Page 2 © Copyright 2003 Storage Technology Corporation (StorageTek) Outline › Mass Storage Technologies › Density Trends for Tape (&Disk) › Capacities/Data rates › Terabytes on a tape › Magnetic Recording › The Media and Heads › Summary

3 Page 3 © Copyright 2003 Storage Technology Corporation (StorageTek) Mass Storage Technologies › Magnetic Tape › Optical Tape › Magnetic Disk › Optical Disk (DVD?) › MEMS Probe › 3D. Holographic, 2-electron… › Other

4 Page 4 © Copyright 2003 Storage Technology Corporation (StorageTek) Magnetic Disk › Technology leader (areal density) › Aggressive storage density growth rate continues but more slowly – 100+% CAGR to 60% or even less CAGR predicted – Still a “spoiler” for other storage technologies › Continued areal density progress influenced by superparamagnetic effect – New approaches to media, heads required, applied, in development Research claims up to 50 Tb/in 2 !? › Consumer products effect development, market, cost e.g. “ATA-class disk” › ATA-class (low-cost) disk can support commercial data processing environment – Utilized in StorageTek’s “BladeStore” disk subsystem with fiber channel rates M. Leonhardt 4-9-02 CAGR: Compound Annual Growth Rate ATA: Advanced Technology Attachment

5 Page 5 © Copyright 2003 Storage Technology Corporation (StorageTek) Magnetic Tape › Technology follower - areal density trend lags disk – Increased defect tolerance – Uses higher media surface area to compete – Volumetric density the tape metric › Continues to leverage magnetic disk technologies as appropriate › Opportunity for more aggressive operating points › Media improvements are key to advancement › 1TB cartridge capacity product roadmaps target 2005-2007 – Multi-TB’s planned › Holding on to cost advantage over other storage subsystems types -- low end under pressure from alternatives. M. Leonhardt 4-9-02

6 Page 6 © Copyright 2003 Storage Technology Corporation (StorageTek) › 10 year outlook has tape maintaining its competitive position with disk (within a narrowed market) – Present capacity, data rate ratios can be maintained – Slow down in magnetic disk density advances factored in -- 60% CAGR – Continuing disk innovation assumed -- gets tougher 5-10 years out Tape vs. Disk -- “Is tape dead?” -- NO!

Spherical particles (e.g. Maxell Nanocap first announced at the INSIC tape meeting at StorageTek Sept 2003) and thin film disk like media extend beyond this.

24 Page 24 © Copyright 2003 Storage Technology Corporation (StorageTek) Summary › Tape continues to lead on volumetric efficiency and $/GByte › Medium has primary impact on the density growth – Magnetic and physical standpoint › Head technology in good shape! › Limit for MP tape ~10Gb/in 2 (Careful!! Disk prediction in 1997 36Gb/in 2 ) › Tape not near any fundamental limits at this time
