I believe the tape is Ampex 456, not positive though. The studio generally bought Ampex 456 tape. It is a ten inch, quarter inch reel (two track master recording). For this collection, we bake 8 hours at 130 degrees. We have found this to be a suitable process for this collection. The shredding appears to be from the edges. We are transferring on a relatively new Otari MX 5050. The machine was cleaned so I don't have pics of the shred. They are usually about 3 inches long before breaking and are about the thickness of fine hair.

Subject: Re: [ARSCLIST] Sticky SHRED
Please provide specifics as to type of tape, width, reel type, baking process and duration.
Also photographs are really useful.
Is the shredding from the edges only or across the entire width of the tape?
What is the playback machine?

> We have a collection of tapes that have sticky shed and we are baking and transferring them. Things are going as planned except for one tape. It is shredding into fine hair like stands. I thought it needed to be baked longer so I baked it a second time. Same problem. I have seen tape shed before and this looks different.
