摘要： Recording means for magnetic data recording which include at least two magnetic materials of different temperature dependency with respect to at least one magnetic characteristic of the same, and a method of operating a device of such type for storing magnetic recording which includes subjecting the recording means, particularly the two magnetic materials of different temperature dependency to the influence of a magnetizing or demagnetizing field.
