searched for it, didn't find it. only found 2 references to a round hub code/serial number, both by you
i've got some TY CD-R media, 2 types, both of them have a straight hub serial number.
- TDK Reflex ULTRA, 24x, 650MB.
- Verbatim DataLife Pastels, 48x. don't know if it's a That's cakebox, sort of looks like it with the bulge down the side, but the base isn't corrugated. got some of these also in slim jewel cases.
is this what you call a That's cakebox?
didn't know there were 2 kinds of the Pastels. but then again i bought these quite a while ago and haven't looked at them closely since. next time i'm in Office Depot i'll look to see if they're 48x or 52x.
as i recall the newer Verbatim Pastels burned better than the older TDKs. but i have to check up on that, it's been a while since i did those tests.
