  • Patent number: 8411534
    Abstract: A data storage device comprises: a light waveguide element; a protective element; and a plurality of data storage elements interposed between the light waveguide element and the protective element. The light waveguide element irradiates light at a critical angle or more on the data storage elements. Each of the data storage elements comprises a transparent ferromagnetic element, which has been magnetized, disposed therein, and the magnetized transparent ferromagnetic element is movable by a magnetic field. When the magnetized transparent ferromagnetic element is moved close to the light waveguide element to allow light from the light guiding element to pass the data storage element, a first data is recorded, and when the magnetized transparent ferromagnetic element is moved away from the light waveguide element to prohibit light from the light guiding element to pass the data storage element, a second data is recorded.
