Hi, Joe, Is this Sony PR-150? If so, it is a known tape that does NOT respond to baking, but I'm not certain if baking exacerbates the problem or not. PR-150 was one of the tapes I tested for my Tape Degradation paper where I introduced the cold playback technique. It also can be transferred with liberal amounts, of D5. Both techniques are discussed in my paper on tape degradation that was originally presented at the Audio Engineering Society's 121st convention in October 2006 in San Francisco was published in the ARSC Journal in the Fall of 2008. It is available here: http://www.richardhess.com/tape/history/HESS_Tape_Degradation_ARSC_Journal_39-2.pdf Further, I have a resource for all to use (and request additions to if they have new info) that lists tapes with known or suspected problems and the known cure (if any). http://richardhess.com/notes/formats/magnetic-media/magnetic-tapes/analog-audio/degrading-tapes/ Cheers, Richard On 2010-11-18 6:22 PM, [log in to unmask] wrote: > I've been attempting to transfer a Sony tape lately, but I am finding > that it seems resistant to baking.
