Abstract: A method of toroid writing and reading of information, consisting in that from toroid-like patterns made from a magnetic material the structures are organized, comprising information and reference patterns, having a closed magnetic flux of the appropriate twisting direction. When writing the alternative information, on changes the twisting direction of the closed magnetic flux in appropriate information patterns by exposing them to the coordinated in the time and magnitude action of mutually intersecting biasing and magnetic reversal alternating magnetic fields, and when reading the information, one acts on the information and the reference patterns by an alternative biasing magnetic field, afterwards detects the output signals and on the character of their responses determines the value of the information unit written into the information pattern.
