Btw.. anybody know what THIS is?

Question is also... due to the weird form "factor" of that CD.... is it safe to put that into a production drive? ; )
Those shaped CD-ROMs were "a thing" in the 90's, buy luckily not for long. Their compatibility with drives were limited to those that one pushed disc to the spindle (mostly portable ones). Some discs would have worked in normal ones if the design of the disc was made so it centered the disc correctly.
Business cards and whatnot shapes were around. Fortunately this madness didn't last long. Some bands released some music on these, but mostly just novelty items that were not meant for use
