• Baking tapes

    From Digital Man@VERT to All on Mon Aug 18 17:11:36 2014
    I'm working on restoring Steve Deppe's old Dresden (and other) recordings on 1/4" and 1/2" reel to reel tape and cassette tapes. Restoration, is initially just digitizing the audio but later remixing, mastering, and possibly replacing
    or adding tracks to bring up to modern standards.

    Anyway, has anyone here heard of issues with Ampex and other reel-to-reel tapes
    of the 70s and 80s having issues delamenating when played back or even re-wound? This is a well known issue (called "Sticky Shed Syndrome" and other names) you can read about here: http://en.wikipedia.org/wiki/Sticky-shed_syndrome

    The popular, but temporary fix, is to "bake" the tapes before playing or re-winding. Here's a good web page about this technique: http://www.tangible-technology.com/tape/baking1.html

    I bought a food dehydrator and plan to begin the baking and restoration process
    soon, but some of the tapes appear to need to be re-wound first (evenly) to avoid overbaking the tape edges.

    I was just curious if anyone else here had been through this process and had tips. Thanks,

    Cool! Sounds like a most-worthwhile endeavor. Best of luck with this.

    It has been. Here's a vlog of my efforts so far: https://www.youtube.com/watch?v=UPn3Gop2h1A

    Now, the first few reels I've played/re-wound after baking still had shed. So I'm re-baking some tapes longer and seeing if that helps.

    Let us know how it will go. I heard that once you bake an old tape, it's good only for one playback, after which the tape is destroyed. I don't know if that's true or a rumor.

    From my experience, that's not true. Many of the tapes I've baked I've had to play through and wind several times to get completely digitally-preserved. The bad tapes do continue to "shed" during this process, but they're not destroyed.
    And from what I've read, after about 30 days, the tapes would need to be re-baked before they should played again (though I have no plans to do that).
