Magnetic domain drawing apparatus

A magnetic domain drawing apparatus, comprising:

• a magnetic plate fixing module including a magnetic plate seating part configured to hold a magnetic plate seated thereon;
• and
• a magnetic domain deforming module disposed at at least one of an upper side and a lower side of the magnetic plate seating part and configured to deform a magnetic domain of the magnetic plate when the magnetic plate is seated on the magnetic plate seating part,
• wherein the magnetic domain deforming module includes:
• a magnetic domain deforming part configured to apply at least one of heat, a magnetic field and an external force to the magnetic plate when the magnetic plate is seated on the magnetic plate seating part;
• and
• a magnetic domain deforming part moving part configured to move the magnetic domain deforming part,
• wherein the magnetic domain deforming part moving part comprises:
• a vertical moving part configured to fix the magnetic domain deforming part and to move the magnetic domain deforming part in a vertical direction, and
• wherein the vertical moving part comprises:
• a bracket coupled to the magnetic domain deforming part;
• a vertical screw threadedly coupled to the bracket and configured to, when rotated, move the bracket in the vertical direction;
• a vertical movement guide disposed in the vertical direction through the bracket so as to be spaced apart from the vertical screw and configured to guide movement of the bracket during rotation of the vertical screw;
• and
• a vertical motor configured to rotate the vertical screw.
