A recording medium made in China initially for backing one revolutionary (10)
I believe the answer is:
microfiche
'a recording' is the definition.
(thesaurus)
'made in china initially for backing one revolutionary' is the wordplay.
'initially' suggests taking the first letters.
'backing' is a reversal indicator.
'one revolutionary' becomes 'iche' (I can't justify this - if you can you should believe this answer much more).
The first letters of 'made in china' is 'mic'.
'for' written backwards gives 'rof'.
'mic'+'rof'+'iche'='MICROFICHE'
'medium' acts as a link.
Can you help me to learn more?
(Other definitions for microfiche that I've seen before include "Filmed record" , "Film" .)
