Roadmap Discussion Magnetic Storage Technologies
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)
Sectors considered • Hard Disc Drives • Media, Heads, Integration & systems • Tape Drives • Media, Heads, Integration & systems • Flexible media • Other storage, security applications
Hard disc drives – nearly 50 years driven by technology Historical progress faster than Moore’s law – several technology revolutions e.g GMR heads.
But the market is changing • Processes and content are becoming • Digital • Mobile • Virtual • Personal • Carly Fiorina, • HP

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
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
INSIC view Reported by Dr Richard Dee – StorageTek
Tape Drives - LTO Update – this is now available
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
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

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.
INSIC material Backup
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
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
