The Future of Magnetic Storage Technologies: Addressing Consumer Demand for Digital Data

As digital consumption surges, consumers are increasingly relying on magnetic storage technologies. The appetite for data has led to predictions of individuals carrying around digital weights equivalent to several trucks of paper. Key players in the industry, like Toshiba and Western Digital, are adapting to shifting market dynamics, faced with challenges in performance, cost, and technology transitions. Traditional media like tape drives face obsolescence, while innovative solutions in hard drives, flash memory, and new storage frameworks are explored to meet the escalating demand for efficient data management.

  1. Roadmap Discussion Magnetic Storage Technologies

  2. Digital appetite – the background • Gadget lovers are so hungry for digital data many are carrying the equivalent of 10 trucks full of paper in "weight". • If digital hoarding habits continue on this scale, people could be carrying around a "digitally obese" 20 gigabytes by next year. • "Britain has become a nation of information hoarders with a ferocious appetite for data," • Martin Larsson, general manager of Toshiba's European storage device division. (9 December 2004 - http://news.bbc.co.uk/1/hi/technology/4079417.stm)

  3. Sectors considered • Hard Disc Drives • Media, Heads, Integration & systems • Tape Drives • Media, Heads, Integration & systems • Flexible media • Other storage, security applications

  4. Hard disc drives – nearly 50 years driven by technology Historical progress faster than Moore’s law – several technology revolutions e.g GMR heads.

  5. But the market is changing • Processes and content are becoming • Digital • Mobile • Virtual • Personal • Carly Fiorina, • HP

  8. Technology alone is no longer enough, but..

  9. Western Digital view (Feb 2004)

  10. Challenges for disc drives • Seamless transition to Perpendicular recording (2005-6) • Write poles, Channels, SUL media • Overcoming conflict between media thermal stability and writability • >2.4 T ?, Coercivity for bit-cell size, ‘Superparamagnetism’ • Head-disc interface • Tribology and surface engineering • Low cost patterned media • Non-lithographic solutions • Drive mechanical performance • Shock tolerance, vibration tolerance, • COST, COST, COST • Demands of Consumer Electronics applications • A personal opinion from Rob Hardeman December 2004

  11. Tape drives • In the consumer, audio, video, broadcasting arena the end is probably in sight for all forms of magnetic tape e.g. cassette, VHS, open-reel: • Mastering – hard discs • Video recording – hard discs & DVD-R. • Audio recording – hard discs, flash, CD-R, DVD-R.. • The growth of broadband communications, Video on Demand, podcasting etc will only accelerate this trend. • Specialist applications will remain but the volume days are virtually over. • In the data world however, things are very different… • “Information Lifecycle management” - ILM

  12. INSIC view Reported by Dr Richard Dee – StorageTek

  13. Tape roadmap – StorageTek

  14. Tape Drives - LTO Update – this is now available

  15. Tape challenges • Maintaining the volumetric and cost advantages • Precision mechanical requirements for high-speed transport • - tape backings, servos, interchangeability • Tribology & wear of head-media interface • - compatibility for removable media • Performance, cost and yield of multi-channel heads A personal opinion from Rob Hardeman December 2004

  16. Other magnetic media • Magnetic stripes Established standards for credit cards, tickets. Market will be eroded by chip&pin, RFID etc but still high volume Unlikely, however, to see significant development.. • Floppy disc Becoming a curiosity – insufficient capacity Drives not being fitted in many PC’s Supplanted by email, USB memory, CD-RW A personal opinion from Rob Hardeman December 2004

  17. Information Storage in the UK http://www.linkisd.org.uk/StorageGuide.pdf (June 2004)

  18. Summary • Magnetic disc drives face many challenges other than technical – it is now a commodity & consumer marketplace. • Technical challenges are focussed on recovering the slope of the areal density curve which has slowed to where near-plateaux are appearing. • Disc drives (magnetic and optical) look to be dominating at the expense of tape. • Other media retain significant niches, but these are reducing with time.

  19. INSIC material Backup

  20. INSIC: TARGETS OF OPPORTUNITY • Increased storage density of magnetic disk, magnetic tape and optical technologies by 10X to 100X over current technologies, including: • magnetic read/write heads • magnetic and optical storage media • head/media interface • signal processing • servo and tracking • optical sources and components

  21. INSIC continued • Advanced manufacturing tools and processes for storage devicesStorage software to improve management and accessibility of stored informationProof of concept of alternative storage technologies with performance potential beyond conventional approaches, including:holographic storage • near-field optical storage • probe storage • solid-state nonvolatile memory devicesStorage system architecture to enable broader and easier application of storage devices to network and non-computer environmentsNew storage-intensive application demonstrations through partnerships with end-users and companion technology providers
