    Materials can store information about their past—like a crease
    in a piece of paper that has been unfolded is a "memory" of being
    folded—that can be retrieved or read out and used for various
    purposes. In everyday life, combination locks must remember the
    turns of the dial to open, and the memory of specialized materials
    is used to make airplanes safer, electronics more efficient and
    bridges stronger and more resilient.

    Now, researchers at Penn State have demonstrated that ordinary
    adhesive tape has a specialized type of material memory capable
    of storing a sequence of multiple memories that can be fine-tuned
    to have different strengths or be erased to make way for new
    memories.

    A paper describing the research was published in the New Journal
    of Physics.

    Heh heh !

    But hey, if you want 'memory', look into all
    those Sumerian clay tablets ... 6000+ years
    and still readable ! Kinda low density alas :-)

    DID come upon an old article about ancient pottery
    though ... once The Wheel was invented the common
    way of adding grooves to the product WAS a bit
    sensitive to environmental sounds. In theory we,
    probably with AI help, may actually be able to
    hear Sumerian voices someday.

    "Information" is hard, theoretically impossible,
    to destroy. All kinds of things can store info
    of various kinds in various ways. Zircon crystals
    MAY hold the sounds of primordial Earth in tiny
    variations those sounds induced during crystal
    formation.
