I need information about how MFM data is encoded.  My computer writes
directly to the disk (It's an amiga by the way) and MFM encoding has
to be done.  Why do I need this info?  I am writing a conversion program
for IBM format to amiga and back.  

How are clock bits added?  Let's say I have an entire tracks worth of
data.  I will need to call a function that encodes this block for the
raw write.  I also would have to be able to strip out all the clock bits
to read my data again (perhaps a verify..)  

I have looked locally for information (Mags and books) but our library
here is very short on quality, up to date books.  (I've flamed them
already! :-)  Any info would be appreciated.
