Re: [ARSCLIST] Fw: [ARSCLIST] Gold CDs

[David Seubert <seubert@xxxxxxxxxxxxxxxx>]

We do use these unique serial numbers to correlate our (unlabeled) CD-Rs
with the cases, which have the label. My reasoning was that in the event
of an earthquake (ahem...) when everything gets knocked off the shelves,
we'll be able to match up the CDs with the cases. These numbers are
recorded in our database as well. Thankfully, when we crawled out from
under our desks this morning there were no CDs to pick up.

All brands we've used over the years (Mitsui, Kodak, Verbatim, Quantegy
and Taiyo Yuden) all have had a printed "number" of varying length on
the inner hub. As Mike says, it can be difficult to read, especially on
T-Y and as CDs become more of a commodity item like toilet paper or
paper clips these numbers have been getting longer and harder to read.
When we started doing this six years ago the numbers were shorter, more
legible and this seemed logical, but these days I might be inclined to
write our own serial number on the inner ring. However, it still works
and we haven't switched yet.
