The invention relates to the technical field of magnetic storage, and discloses a magnetic storage device and method based on AC voltage assistance, and the device comprises a storage medium which is provided with a ground electrode at one end and is covered with an insulating layer at the other end; the magnetic head is positioned on the storage medium and is provided with a positive electrode for applying alternating current voltage; and the alternating-current voltage source is electrically connected with the positive electrode of the magnetic head and the ground electrode of the storage medium and is used for providing alternating-current voltage matched with the resonance frequency of the magnetic medium. According to the magnetic storage device and method based on alternating-current voltage assistance, the alternating-current voltage is introduced to assist magnetic moment inversion, so that the required magnetic field is remarkably reduced, and a storage medium with high anisotropy can realize inversi
