Recordings of temperature — with copies (5)
I believe the answer is:
tapes
'recordings' is the definition.
(I know this)
'temperature with copies' is the wordplay.
'temperature' becomes 't' (abbreviation).
'with' is a charade indicator (letters next to each other).
'copies' becomes 'apes' ('ape' can be a synonym of 'copy').
't'+'apes'='TAPES'
'of' is the link.
(Other definitions for tapes that I've seen before include "Records - strips of material" , "A spate of magnetic records" , "Bands of fabric" , "Long thin pieces of cloth or paper" , "Magnetic strips for recording" .)
