"Audio" CDR
I'm one of a few who own a standalone CD recorder, which is handy for transcribing LPs but crippled requiring so-called Audio or Music CDR blanks. These are identical to data CDRs but have a sort of spoiler code on them and cost around 40p more per disk than data CDRs. That's if you can find them.
The extra cost is, in part, a levy to the record industry to appease their panic that CD Recorders would be used to copy their artists' CDs. Of course, nobody uses them for that because it's as easy to do it on a computer you already have and you save paying £200 for a CD recorder and a 40p tax on every blank disc.
The irony is that the only other people I know who use CD recorders are musicians recording their own work. So most of the people paying the levy are musicians, effectively being taxed for recording music to which they already own the copyright.
