Biblical figure's end, after brief record period (7)
I believe the answer is:
ephraim
'biblical figure's' is the definition.
(figure in the book of Genesis)
'end after brief record period' is the wordplay.
'end' becomes 'aim' (both can mean a purpose or goal).
'after' means one lot of letters go next to another.
'brief record' becomes 'ep' (abbreviation or 'brief' form of Extended Play).
'period' becomes 'hr' (abbreviation for hour).
'ep'+'hr'='ephr'
'aim' put after 'ephr' is 'EPHRAIM'.
(Other definitions for ephraim that I've seen before include "Joseph's lad" , "tribe" , "Biblical people" .)
