Record binder (4)
I believe the answer is:
tape
I believe this clue is a double definition.
'record' is the first definition.
('tape' can be a synonym of 'record')
'binder' is the second definition.
(thesaurus)
(Other definitions for tape that I've seen before include "The finish line" , "Music cassette" , "Sticky strip" , "Record; material strip" , "This is often stretched across the finishing line of race" .)
