Find out about record surplus (8)

I believe the answer is:

discover

'find out about record surplus' is the definition.
(I've seen this before)

'record surplus' is the wordplay.
'record' becomes 'disc' ('disc' can be a synonym of 'record').
'surplus' becomes 'over' (I've seen this before).
'disc'+'over'='DISCOVER'

(Other definitions for discover that I've seen before include "Realise" , "Uncover, find" , "Be first to observe" , "Find during a search" , "Find unexpectedly" .)

I've seen this clue in The Guardian and The Telegraph.
