Piece of spinal cartilage (4)

I believe the answer is:

disc

(Other definitions for disc that I've seen before include "'Round, flat shape (4)'" , "Thin circular plate, as in CD" , "Compact ---; slipped ---" , "Layer of cartilege between vertebrae" , "Thin flat circular object" .)

I've seen this clue in The Times.
