Re: [ARSCLIST] scotch 227

Hello,
I've been reading the list for while and appreciate the information and
knowledge that is shared here, and I have a question about a particular
brand/stock of tape.

Most of our recordings made in the mid-late 80's and easrly 90's was
recorded to Scotch 226. It's all pretty sticky, but bakes well. I have
just encountered a single reel of Scotch 227. It seems to be a thinner
tape than the 226, ad Im assuming it was an economy version of 226. It
is also sticky, however it does not respond to baking. While the amount
of deposit left on the heads and guides is minimal, and the tape passes
through the transport without slowing, the squeal and distortion is
audible in the transfer.

Does anyone have any experience with this tape? Any suggestions or other
treatments that might get it to run smoothly?


Hi, Mike,


227 was the 1-mil (longer play) version of 226 if I recall correctly. It's the same with 202/203, 206/207, etc.

1-mil was very useful for concert recordings as a 10.5-inch reel would provide 45 minutes at 15 in/s rather than the 30 minutes with the 1.5 mil "standard" tape. It wasn't generally done for economy, but for allowing more uninterrupted running time.

How long have you baked these tapes? 12 hours at 130F is the current suggestion.

You may find information here http://www.aes.org/aeshc/3mtapedoc.html useful about 3M tapes.

Cheers,

Richard
