Hi my name is David. Welcome to Just Answer. I am reviewing your question and will reply ASAP.
The problem sounds like the slot is blocked. It could be the dust cover blocking the eject.
There is a method of ejecting a stuck disc using a credit card or stiff piece of card. I have had success with this method in the past.
It's tricky to describe, so I will link a few documents that show how to do it.
Try with one card first. Put a small bit of pressure on the disc inside the slot loading drive. Then try the eject.
Let me know how it goes. Thanks in advance,
