Tapes the best performance of all time (7)

Ross

I believe the answer is:

records

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

'tapes' is the definition.
('record' can be a synonym of 'tape')

'the best performance of all time' is the wordplay.
'the best performance' becomes 'record' (I've seen this before).
'of all time' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'record'+'s'='RECORDS'

Can you help me to learn more?

(Other definitions for records that I've seen before include "Makes written note" , "Discs" , "The best (or worst) performances ever" , "Sets down in writing or preserves in sound" , "Annotations of events" .)
