[ale] burning blu-ray discs

[Jim Kinney]

The m-disk reads like a Cd/DVD/Blu-ray but the data doesn't degrade. It's
extrapolated lifetime is 1000 years based on Navy stress testing.
It's only for archival storage. Uses a special burner (that doesn't cost
but maybe a few dollars more than a normal one) to write the disks. Any
reader can read them.

Typical lifetime of a spinning disk (in use) is 5-8 years (for enterprise
grade, 24-7 on line). Tape's can last 20-30 years with proper storage (LTO6
2.5TB is rated for 30 years with proper storage and costs $60/tape - the
drive is $4k)

The mdisk is a specialty archival media. Think financial records, tax
records, family records, etc. or 42 thousand pictures of your cats per
blu-ray disk :-)

Every time you stop a school, you will have to build a jail. What you gain
at one end you lose at the other. It's like feeding a dog on his own tail.
It won't fatten the dog.
- Speech 11/23/1900 Mark Twain
