Changes began to take place in the manufacturing of magnetic tape in the early 1970s. With time, these changes have proven to be problematic. The first issue was diagnosed as “Sticky Shed Syndrome”. Fast forward to today, magnetic tapes are showing other signs of degradation that had rarely or never been seen before. During this session, we will discuss issues such as “Adhesion Syndrome”, “Loss of Lubricant” and “Binder Disintegration”. The worst being “Binder Disintegration”, when the oxide side of the tape is no longer bound to the base material. The media just falls apart and is permanently lost. While this issue seemed beyond repair until recently, new approaches uncover possibilities for reconstructing and recovering the recordings, which would otherwise be considered lost forever. We have teamed up to address such issues with emerging technological developments that are based on synchrotron X-rays. These polarized X-rays are being used to develop a unique readout method for the recovery of audio signal from magnetic tapes. This method reads the magnetic information stored on the tape without contact. This is in stark contrast to a playback head, which places the tape under mechanical stress. The X-ray method extracts the raw audio signal written to tape before equalization. We have successfully demonstrated signal recovery from aged and damaged tape, as well as from tapes suffering from sticky shed syndrome (without baking).\u003c/p\u003e"]}},{"label":{"en":["Publisher"]},"value":{"en":["Association for Recorded Sound Collections"]}},{"label":{"en":["Rights Statement"]},"value":{"en":["\u003cp\u003eCopyright Association for Recorded Sound Collections\u003c/p\u003e"]}},{"label":{"en":["Language"]},"value":{"en":["English"]}}],"summary":{"en":["\u003cp\u003eThe 1950s through the 1980s was the era of magnetic tape.
