Disc that may be broken (6)
I believe the answer is:
record
'disc' is the definition.
(I know that disc can be written as record)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for record that I've seen before include "Written report - best so far!" , "Set down in writing" , "Written account of proceedings" , "Set down in permanent form" , "that has been cut" .)
