Preservation Problems with A Director Game

[orange]

I grabbed myself a cheap physical copy of an old Tivola game.
To preserve its contents for longer than the disc lasts (it is 20 years old already) i wanted to create myself an iso image.
It looks like this old childrens game (TKKG :Panic in a boarding school) is trying to defy my archive process with copy protection though.
It is sitting there since almost 20 spewing out "bad block" errors and there is a clearly visible ring on the outer edge of the cdrom.
Are they really using securom&Safedisc on these games (no label visible with a magnifying glass) ?
What do we use these days to solve this?

should normally be enough, otherwise maybe look for one that can skip those bad blocks

You sure it's not plain old disc rot?

On a few hundred sectors in a row that you can clearly see as a light ring on the disc? Possible but unlikely
