Disk drive technology

[Tom Jennings]

Stumbled upon this while looking for something actually useful
(eg.  disk drive reliability data -- yeah right). Its more or less
market hype, mainly the forward projections, but the interesting
part are some good drawings of head topology,
density-over-the-ages charts. Good drawing of perpendicular head
design.

IBM by way of Hitachi.
