Paul Pierce built something similar to what you did for recovering
7-track
data, and discovered that you really need to recover the data using
analog
techniques to get any reliability.

Thanks for the offer. I will see how we get on using the original
hardware
first. The decks have ten tracks so I guess I would need two of them.
Each
frame contains 4 bits of data and six error correction bits so I am
hopeful
that the original hardware, after recalibration etc, will be able to
read almost
all of the data, and where we can't, at least know which frames have
errors in them.
