A search of Bandcamp and CDr or CDBaby and CDr will get even more examples on Discogs. I've literally had to tidy up thousands of them which were incorrectly added as CD.
I've a ton of other CDrs, which have been made by record labels etc for small runs. Sae principle I think:
I come across a dozen or so of these every day, mistaken for CD -

This CDr was from Westwood one. They sell broadcast CDr to licensed broadcasters. They also transfer files if required instead.
This one is from the Merge record label. It's quite common. 80PG and 80PMs are everywhere. There's quite a few variations on the the first two letters that we come across.
You must recognise these, also find older ones using R015 up to R049...basically write speed, which you'll know) - they're not as popular as they used to be.

Indie band handed me two promos. This and the one underneath. I know this is a repeat of another above, but it just goes to show that duplicators have no brand loyalty.
CDR 80 CWLHT-1229 C102
CDJ 76T MBI 80UG

If you go to advanced search and enter 2016 in the year, CDr in the format section and sort the results by most recent, you'll find modern examples of what people are using.
