Title: Roadmap Discussion
1Roadmap Discussion
- Magnetic Storage Technologies
2Digital 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

3Sectors considered
- Hard Disc Drives
- Media, Heads, Integration systems
- Tape Drives
- Media, Heads, Integration systems
- Flexible media
- Other storage, security applications
4Hard disc drives nearly 50 years driven by
technology
Historical progress faster than Moores law
several technology revolutions e.g GMR heads.

10Challenges for disc drives
- Seamless transition to Perpendicular recording
(2005-6) - Write poles, Channels, SUL media
- Overcoming conflict between media thermal
stability and writability - gt2.4 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
11Tape 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

14Tape Drives - LTO
Update this is now available
15Tape 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
16Other magnetic media
- Magnetic stripes
- Established standards for credit cards, tickets.
- Market will be eroded by chippin, 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 PCs
- Supplanted by email, USB memory, CD-RW

18Summary
- 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.

20INSIC 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
21INSIC 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
