Note recorded as beaten (7)
I believe the answer is:
flogged
'beaten' is the definition.
(flogging is a kind of beating)
'note recorded' is the wordplay.
'note' becomes 'f' (musical note).
'recorded' becomes 'logged' (logging is a kind of recording).
'f'+'logged'='FLOGGED'
'as' acts as a link.
(Other definitions for flogged that I've seen before include "Lashed -- sold" , "Beat severely or sold" .)
