Well, you asked for "any comments" ...
I worked with a nonprofit radio interview group and we tried one
batch of DAK tape - the quality was so bad we threw it out right
away. Then we settled on buying "Shamrock" 7" reels of substandard,
factory reject Ampex at $1 each in boxes of 50, and spent time
sorting backcoated from non coated, splicing them into 10" pancakes,
and so on - within ten years 90% of it turned sticky, forcing me to
learn baking techniques long before I knew anyone else using it... So
we might have been better off with the DAK!
Later we switched to 3M 176 (duplication grade) for our masters (!)
and while not premium, all the 176 still plays faultlessly. I never
seem to hear abotu 176 and 177 here but it never shed or got SSS. 176
is like a newer 111, which also always plays when I get it in... if
it doesn't break!

x1/4 and 10x1/2 inch tape. Stored with out regard for heat and cold.
I pulled some of this stock since this sss discussion and the 3M
stock from the 60-70 doesnt seem to show any sss. The same goes for
computer even the backcoated.
I would think that the binder would be the same for
audio/computer/instrumentation/video tape coating lines would be

Any comments ?
