This may not be the appropriate newsgroup for digital tape recording, but...
The record amplifier in my stereo cassette deck is on the fritz, and since it
would probably cost me half the $100 I paid for it to get that 14-pin IC
replaced (out of warranty one week, of course!), and since I *did* get it for
its logic-control solenoid transport for possible future integration with my
home computer, I am contemplating ripping out the analog circuitry and
doing saturation recording on standard audio cassettes.
I have access to one respectable-looking library book on magnetic tape
recording techniques, covering everything from hysteresis to GCR, as I
recall. I understand that saturation recording does its own erasure, so I
was contemplating using the erase head to do the recording, which would free
the normally record/playback head to be playback only, allowing read-after-
write verification.
I am also wondering if saturation recording results in lower bandwidth for a
given tape/head combination than non-saturation recording would; I don't have
the expertise to tackle any exotic modulation/demodulation techniques like QAM,
simplicity is the key here.
Has anyone ever attempted such a feat? Do you know any pointers that I would
be unlikely to find in a book? Am I suffering from a bad case of cranio-rectal
impaction?!
Please respond via Email; my newsreading time will be sharply curtailed for a
month or so.
Thanks in advance... -Charles Green
