Scanning Disc Negatives
Many years ago Kodak, and other film / camera makers, introduced a new type of ultra-compact cameras.
They featured a very small lens combined with a tiny piece of plastic. These two features supported a very short light path so the camera was very shallow, ideal for a pocket or handbag. As you can see from the photo the negatives were mounted on a wheel, which clicked round operated by a lever after you’d taken a shot.

From the experience of a couple of relatives results were often poor. It was very difficult to keep the camera steady and combined with such a small negative meant it was hard to get good prints or any degree of enlargement.
Overall the whole thing was not a great success and disc negatives are now a distant memory for most of us.
But yes, we can scan them, and this is what they look like.
