Daughter going into revamped classier data storage system (5,4)
I believe the answer is:
laser disc
'data storage system' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'daughter going into revamped classier' is the wordplay.
'daughter going' becomes 'd' (I've seen this in other clues).
'into' means one lot of letters goes inside another.
'revamped' indicates an anagram.
'classier' with letters rearranged gives 'laserisc'.
'd' placed inside 'laserisc' is 'LASER DISC'.
Can you help me to learn more?
(Another definition for laser disc that I've seen is " Flat data-storage device".)
