Talk of erasing us from the records (5)
I believe the answer is:
discs
'the records' is the definition.
('disc' can be a synonym of 'record')
'talk of erasing us' is the wordplay.
'talk of' becomes 'discuss' (discussing is a kind of talking of).
'erasing' suggests deleting specific letters.
'discuss' with 'us' taken away is 'DISCS'.
'from' acts as a link.
(Other definitions for discs that I've seen before include "Layers of cartilage between vertebrae - they may slip" , "Flat, thin circular objects" , "Type of recordings" , "They're round and flat" , "Records" .)
