Hi and be welcome on our forums!

There can be quite some reasons why these discs cannot be read. The most likely is that your media has degraded during the years. That doesn’t imply that your media isn’t usuable at all; it might be that other readers can use the media just fine. The reader in your laptop ain’t the best on the planet (sorry, I know… got such a drive too) and really doesn’t know how to handle somewhat degraded media. The best would be to try your media in other drives and see what happens. If that works, it could be wise to backup those discs on another computer.
