Hi and welcome to the forum
That drive is not exactly a recent piece of hardware, so my guess is that there is some dust on the optical pickup causing difficulties to read discs. To clean it is needed to open the drive and clean lens with a proper detergent (alcohol is fine), but if you don't want open the drive there are some purposely made cleaning kits available in stores
Another possibility is that the disc you are trying to read is scratched or dirty, or unreadable for some reason. Can you test these discs in another drive? If no drive can read these discs, then the drive has no problems.
Alternatively, the drive can be damaged, and the only solution is a new drive
