With the release of this strain, lateral displacement (displacement in the width direction of the medium) occurs in the medium, and a phenomenon occurs in which the entire shape of the wound medium is spirally displaced. In other words, over time, the overall shape of the wound medium transforms into a so-called bamboo shoot.
