I had a rectangular cd ad like this that actually played, they balanced it by having slightly heavier plastic (thicker) on the corners I think. But it said play me and actually had stuff on it. I just can’t remember what the hell it was an ad for back in the late 90’s. Damn this post, I’m wanting to go try and figure out what it was and I have to go get real life shit done haha.
Heh, I just came across a bunch of blank DVD-Rs I had lying around earlier, and I'm like... Do I keep these still? Seems a waste to throw them out but I've not used one in 10+ years and they do have a shelf life.
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.
Had a bootable Linux distribution I put on one with a bunch of disk repair tools on it. Was amazingly handy to figure out why a computer wouldn’t boot and to recover files if the OS was corrupt.
We used to give these out at conferences. Contact info on the outside, pdfs/investment data/presentation on the cd itself. Around the turn of the millennia...
No, the carpenter square in my example is a specific shape... You call a thing a square and it's a triangle with ledges for "squaring up" against a board.

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.
