  • Magnetic domain drawing apparatus
    Patent number: 11331932
    Abstract: A magnetic domain drawing apparatus includes a magnetic plate moving module including a magnetic plate seating part configured to hold a magnetic plate seated thereon and a magnetic plate moving part configured to move the magnetic plate seating part, and at least one of magnetic domain deforming modules disposed to be spaced apart from the magnetic plate seating part at a predetermined distance and configured to deform a magnetic domain of the magnetic plate when the magnetic plate is seated on the magnetic plate seating part. The at least one of magnetic domain deforming modules is configured to deform the magnetic domain of the magnetic plate by applying at least one of heat, a magnetic field and an external force to the magnetic plate.
