Strange Old Disk

I've spent hours upon hours trying to figure out what exactly this is but the closest thing I can get to it is an RL02 removable cartridge disk, but it's not (I think)! I don't see how the same drive could read these since the holes are so much different, but it's the same general idea. I'm not sending attachments, I put them on a site for you to look at, the url is http://www.spiritsphere.com/14inchdisk.html , any and all information you could give me about this disk would be greatly appreciated, I'm still in the dark about it, and have found very little reference at all to CDC ever making a cartridge like this. Thank you! Best Wishes :) Tim
