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.

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…

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

Other magnetic media

1. 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..

2. Floppy disc
   Becoming a curiosity – insufficient capacity
   Drives not being fitted in many PC‟s
   Supplanted 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.
