Super high speed recording method?

["Thomas Ashcraft" heliotown27]

Question :  I want to do some *super* high speed audio recording and 
wonder what sort of technology is available for this these days?  Is 
anything available to the "prosumer" maybe?

My application is to audio record Jovian radio bursts and then look as 
deep as possible into one second's worth of time. I have seen 
spectrographs of audio recordings where they ran tape at many  many 
inches per second. ( I can't remember exactly how many inches per second 
but maybe 100 inches or maybe 300 inches per second . Not sure about the 
actual speed but *fast* in any case. )

I thank you in advance for pointing me to any information or resources.
