Here are some of the suggestions I got from Googling your question:

Take a pair of needle nose pliers and a small flat head screwdriver. Put the screwdriver under the bottom and pull upon the tape with the pliers and pull it out.

TRY HOLDING DOWN BOTH REW & FF @ SAME TIME, OR HOLD EJECT WHILE USING PLYERS & SCREWDRIVER, (tape is prob destroyed & player will only eat more tapes U may want to think about replacement).

Slowly give the cassette a lift using a small screw driver while pressing the eject button. Once the cassette is out carefully and slowly pull the tape so it won't break.

Use a butter knife. Try to ease it upward and then out. The ribbon is probably tangled around the back spool. If this is the case, that particular cassette will never play properly again.

Insert a thin, flat-head screwdriver beneath the cassette tape inside the deck. Gently pry upward on the tape until it comes free from the tape deck's heads. Grasp the tape with a pair of needle-nosed pliers. Pull the cassette out of the deck.

Lift the tape out of the deck slightly and untangle the tape from tracking mechanism inside the tape deck. This method only applies to tapes that are tangled up inside the cassette deck.

Grasp the cassette with a pair of needle-nosed pliers, and gently rock the cassette back and forth until the cassette disengages from the tape deck's heads.

Loosen the Phillips-head screws on the outside of the tape deck's casing. Remove the cassette deck's housing until the stuck cassette tape head is revealed. Pull the cassette tape out of the deck.
