I once was caught in a "didn't have one of those junkie tabletop 
recorders" situation and had to use my good hifi deck to make a tape 
for someone. I recorded on only one of its 4 channels.  That person 
reported the same thing I found, I could recover that tape error-free 
as long as it was fed to the coco loud enough to be heard on the 
hifi.

I made several more tapes by that method, and everyone of them was 
absolutely bulletproof.  The biggest problem is not having a motor 
control interface, so you had to be well synchronized.

Those so-called computer data recorders they sold us were basicly a 
POS, often using a magnet for tape erasure, and always using a direct 
current bias method instead of a 100khz power oscillator.  The 
resulting signal to noise ratio was predictable, and often didn't 
exceed 10db because of the horrendous hiss you get from using a dc 
bias.  Record on something with a decent signal to noise ratio, and 
the playbacks are simply bulletproof.

Just because it said 'computer' or 'data' on it someplace, we were 
charged an extra 50 bucks for a 30 dollar recorder.
