Record reader and writer (6)
I believe the answer is:
stylus
This clue is a double definition.
'record reader' is the first definition.
(point used to read a vinyl record)
'writer' is the second definition.
(I've seen this before)
'and' is the link.
(Other definitions for stylus that I've seen before include "Engraving instrument" , "One going on record" , "Old writing implement" , "LP tracker" , "Pointed tool for writing" .)
