what happens if you record a type I cassette on type II setting, and vice versa?

After delving into the deepest recesses of my memory, I remember the differences being almost entirely that of EQ and Tape Hiss. And oh yeah...  Go back to the proper settings if acrid smoke begins to waft.............

thanks for the replies guys!

I am in a band, and I have this really great cassette deck for whenever when play, and we love to hit record on a good tape (Fuji and tdk are my preferences) and let it roll all night! 

and last night i almost forgot to turn off the CrO2 / type II setting, and I was just wondering what would happen IF i
"record a type I cassette on type II setting, and vice versa".

which leads me to another question...

what is the best cassette tape maker in your experience?


I'll also be making a new thread with this question.

Best cassette tape makers ... I did well with TDK & Maxell for Type II cassettes.  BASF was also ok for Type II.  Never did much recording with Type I or IV tapes for that matter.

AudioGon used to be a reliable source of information…

Assuming you can set the record EQ on your deck (and it’s not automatically set via the physical notches on the cassette) it’s generally best practice to record on both Type I and Type II media using the 120us setting (also, assuming you can set the bias).
