I believe the answer is:
discs
'hockey-puck shapes' is the definition.

This is the entire clue.
(Other definitions for discs that I've seen before include "Records" , "Layers of cartilage between vertebrae - they may slip" , "Type of recordings" , "Flat, circular plates" , "Flat, thin circular objects" .)
