I believe the answer is:

tape

I'm a little stuck... Click here to teach me more about this clue!

'record?' is the definition.
(taping is a kind of recording)

I don't understand the rest of the clue.

(Other definitions for tape that I've seen before include "The winning runner breasts the ...." , "Record - broken by the winner" , "Band" , "Race finishing-line" , "Record; finishing line" .)

I've seen this clue in the Evening Standard.
