Minute disc (6)
I believe the answer is:
record
I believe this is a double definition.
'minute' is the first definition.
(I have seen 'A minute' mean 'record' so perhaps 'minute' could also mean 'record')
'disc' is the second definition.
(I've seen this before)
(Other definitions for record that I've seen before include "Best sporting performance ever" , "LP or single?" , "Make a single" , "Note - disc" , "Write down; music disc" .)
