Data recovery

I found an old disk with the first trip to the mountains. The material on the disc is unique and is not found anywhere else.

The disk is in poor condition. Video on disk. One piece or several - I do not remember.

There is some sticky nonsense and a crack on it.

A photo

1. Is it possible to recover something from this disk? Houses?
2. Is it possible to insert it into DVD-rum in this state at all? Or something to clean first? How? What about crack?

Read data with Non-Stop Copy. He is guaranteed to ignore the broken sections and even try to read from them everything that is possible.
It is better not to spin more than 2x, because the disk is not symmetrical and can jump or even scatter.
The damaged place (is it corroded by some kind of liquid, it seems?), Perhaps, it cannot be returned - most of it has been eaten right up to aluminum.

DVD discs have an "information layer" between two layers of polycarbonate, so it's often enough to clean the bottom surface gently. Apparently, from one edge the disc has delamined at the junction of the polycarbonate and information layer, nothing can be done about this stain. Clean from the center to the edges, avoiding circular motions, with a soft, lint-free cloth. It is better not to use aggressive chemicals, as an option with fairies or warm soapy water. From the software, you can try BadCopy.

With a crack, it is not clear from the photo - is it a large side chip (I have never seen anything like this on disks) or what?
In general, first wash the disc, you can with soap, gently wipe with a non-abrasive sponge. When all the rubbish is washed off, try to shove it into the drive. Discs are read from the center, so there is a chance that most of the data can be read without problems.
Zapadlo maybe, if there are several sessions on the disk and the drive (OS) immediately starts to go around everyone, I get into an unreadable area. But from the photo you seem to have everything recorded in one session.
Yes, it would be nice to immediately limit the reading speed with some utility so that the disk does not spin up much.

A good option is to freeze it all to -35 in the refrigerant of a local store, and then remove everything that is on it on sticky there, and go out into a warmer room, insert it into a laptop, where there is a drive that can adjust the speed
Then set the lowest speed and programs from previous posts to read the disc.
Another option is to polish the disc at some local factory or workshop where mirrors are produced, and then read it, again, it’s better in the cold, I don’t really understand why the discs read better in the cold, but this is a fact. (Perhaps due to microcondensation that smoothes bumps)

The disc can be polished at home with toothpaste and flannel. I've done this myself a few times - always lucky.
- wash the fairy disk
- place a piece of toothpaste on a clean piece of flannel
- rub the surface of the disk with gentle pressure, long and with feeling. It makes sense to wash off the paste every 10 minutes and try
. Naturally, the disc cannot be scratched from the wrong side - since the foil is located there.

Well, how to prepare a disk is already written here.
Here is an excellent manual for recovery, I recently used it myself.
