archival cd-r - really true?

Judging from the time it takes my drive to seek to other tracks, which is
nowhere as fast as the seek rate of my hard drive, I suspect there;s some
sort of search algorithm being used.   And regardless of the drive, if the
inner tracks are damaged, there's an excellent likelihood that the drive
will refuse to mount the CD.

How about this as an arbitrary test of the recoverabiliy of a medium?  What
I call the "pinking shears" test.  Maybe some remember it from an episode
from "The New Detectives" TV series.

Take the medium and cut it into randomly sized peices, with the mean being
about the size of a postage stamp, using pinking shears.  Pick up most, but
not all, of the peices, throw them into an envelope and ship them across
the country.  How much data can you reconstruct from the fragments?

You know, floppies aren't all that bad for storing data...

Cheers,
Chuck
