Default Flight Data Recorders

MAK adds that the quality of the flight-data recorder information
is "unsatisfactory" because of partial thermal damage to its
magnetic tape, caused by the intense fire which followed the crash.


Which made me think: magnetic tape?! Surely we've come far enough that
we can be using solid-state storage in flight data recorders?


Does anyone know why FDRs would still be using what, to me, is archaic
technology?


Co$t is why. And while flash-based systems may offer more survivable
recording; consider the recent Qantas incident, where the
depressurization itself was overwritten by subsequent flight.
