An ISO is essentially the contents of an ISO-9660 filesystem (or UDF, in
the case of some DVDs).  Most of the contents of the disk is a squashfs
filesystem (compressed) are deb packages, which are compressed using
gz/bz2/lzma/lzma2, so re-compressing them would be marginal at best.  Long
story short, the people distributing the disks aren't trying to bump up
sales of DVD-Rs, the things included are just getting bigger.  Probably due
to crap like Unity and the Amazon Search Lens, but that's the story.

Use silver or gold-based dye, not organic, if you want to archive data.  I
personally think it's much faster to put installation media on flash than
on optical media, and I sure don't care about archiving a Ubuntu install CD.

My feelings on this are similar to those regarding using badblocks on a new
drive: that's what backups are for.
