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)

A personal opinion from Rob Hardeman December 2004Magnetic RoadmapDecember 2004 Rob Hardeman Page 10

Tape drivesIn 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…

Tape Drives - LTO

Update – this is now available


Tape challenges

Maintaining the volumetric and cost advantagesPrecision 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

1. Magnetic stripesEstablished standards for credit cards, tickets.Market will be eroded by chip&pin, RFID etc but still high volumeUnlikely, however, to see significant development..

2. Floppy discBecoming a curiosity – insufficient capacityDrives not being fitted in many PC’sSupplanted by email, USB memory, CD-RW

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: 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 continuedAdvanced manufacturing tools and processes for storage devices

Storage software to improve management and accessibility of stored information

Proof 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 devices

Storage system architecture to enable broader and easier application of storage devices to network and non-computer environments

New storage-intensive application demonstrations through partnerships with end-users and companion technology providers
