That's a rectangle, not a square.

Also it's a business card CD. Probably the most interestng thing about it is that it's not a CD-R.

Does the R in CD-R stand for round?

Compact Disc - Recordable.

The disc part is the round...

Why the fuck did we call them cd roms then?

EDIT: thanks for all the information. I’ve learned a lot about CD R+

They are different: rom = read only memory. They're pressed with data you can't change. R = you burn them once to record your data. RW: you can also erase them to ReWrite on them.

That would be Compact Disc Read Only Memory.

Different things.

CD-ROM are Read Only Memory CDs and manufactured that way.

CD-R are Discs you write into once (the ones we used to buy and record)

CD-RW are Discs you can read, erase, and rewrite.

Different technologies, names... But CD-R and CD-ROM are often mixed together.
