A magnetic material such as iron is said to be saturated when it cannot be magnetised any more. This is undesirable in a transformer or an inductor as its performance is then reduced. But in digital magnetic recording (in a hard disk or a digital tape) the surface is deliberately saturated in order to reliably record ones and zeros.
