Tim,
That appears to be a fairly common disk pack as used in drives such as
an DEC RK05 and similar. There were a number of drive manufactures who
used that style of disk pack. The number of notches (sector markers) in
the bottom metal hub ring will give a better idea of what machine the
pack was likely used with. Also, if there is a density marking, that
would also help.

I picked this disk up the other day knowing almost
nothing about
mainframe storage methods. 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

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 :)
