I was only suggesting it for the legend side, not the data side - as
an alternative to lightscribe.


They used to make optical media with the printable label area
on it, for use with inkjets. The inkjets that had a provision
for writing on optical media. But try and find an inkjet today
that writes those. That's what we had before LightScribe,


Oh, I hadn't been aware that they'd stopped doing them.

and the people who had the proper printer, seemed to like that
scheme. It wouldn't upset the balance of the media, like
a paper label would.


I never actually had any problem with paper labels, when applied with
one of the various things that applied them.

The problem with LightScribe, was it took as long to burn
the label, as to burn the data bits. A "single pass" wasn't


Probably longer, given the up-to-5x-times speed of modern drives.
(Though I don't think I've ever burned a CD at max. speed - I feel
they're likely to be more reliable if burned at a lower speed.)

dark enough, so the burn process had to be repeated multiple
times until the desired shade was achieved.


My first thought was that it must be difficult aligning the passes, but
I assume you mean they're all done in the one session (i. e. CD not
removed from drive between them).

I wonder if my idea of a spray-on coating - for the labelling side, to
avoid any doubt - has any legs! The chemical could be made _more_
sensitive than lightscribe discs, if it was a two-part process involving
a "fixing" spray to be applied afterwards (either to block the relevant
wavelength, or to stop further change in the chemical, as in
photographic fixers. [Or both.])

If it ain't broke, fix it 'til it is.
