Re: [ARSCLIST] Tape baking question

["Richard L. Hess" <arclists@xxxxxxxxxxxxxxx>]

Hi, David,

I invented the cold-playing process--put the player in the fridge  
along with the tape...I presented that Sunday at the AES in San  
Francisco.

Tapes that do not respond to baking and still squeal such as Sony  
PR-150 and 3M 175 do respond to being played below their current glass  
transition temperature (Tg). The binder degradation has lowered the Tg  
to below room temperature.

Cold-desiccation, as I understand Peter's process, is different. I  
don't think he plays the tape cold.

It seems we're all incoherent. I'm in western Nebraska on my way back  
from SF. Tomorrow I pick up yet another tape recorder in Des Moines.

Cheers,

Richard
