the data is gone for good
as for the PS3, well obviously it looks like the Br drive is broken or (if you are lucky) the laser lens is just dirty
try to play BR movies/DVD movies and games from the hdd (which should work) to confirm that suspicion
try to clean the laser lens and if that doesn't improve the situation you probably have to look on ebay for a PS3 BR drive for that particular PS3 model (there should be several listings for that)
