Abstract: A method of recording in a Bloch-line memory and/or of reproducing from the same is specified. In this method, light beams are transmitted or guided to the vicinity of a free end of a magnetic domain which is suitable for the development of a Bloch line in the same, or onto an extension line of the same.

Abstract: In a process or system for displacing Bloch lines, in one step only a first Bloch line of a pair of Bloch lines in a magnetic domain wall is displaced in a predetermined direction and in another step the second Bloch line of the pair of Bloch lines is displaced in the predetermined direction in order to form the pair of Bloch lines. Typically, in a first step a magnetic field perpendicular to a plane of a magnetic thin film containing the domain wall is set up at the thin film and in a second step a magnetic field parallel to the plane of the thin film is set up at the thin film along the domain wall.

Abstract: In a process or a device for determining the presence of a Bloch line in the domain wall of a magnetic domain formed in a magnetic thin film, a magnetic field is set up at the magnetic domain parallel to the plane of the magnetic thin film and induces a change in the magnetic domain, the state of which change is sensed and the presence or absence of a Bloch line at a predetermined point of the domain wall is determined from the result of this sensing.
