发明名称 Flexible media magnetic printing system
摘要 A flexible media magnetic printing system provides for data storage within flexible media imprinted with magnetic ink. In a particular embodiment, the printing system includes at least one reservoir of magnetic ink with magnetic particles capable of supporting high density data, and at least one reservoir of visible ink. The reservoirs are coupled to a print head including one or more ink-ejecting nozzles, which is removably or fixedly coupled to at least one magnetic read/write device. The magnetic read/write device tracks above the magnetic ink applied by the ink-ejecting nozzles to the flexible media. The magnetic read/write device writes to the magnetic ink by providing a magnetic field of sufficient intensity to re-orient the magnetic alignment within the ink to a known direction. The magnetic read/write device also reads data from flexible media, for example, paper or cloth that is imprinted with data-embedded magnetic ink. Visible or substantially invisible magnetic ink may be applied as dots within or strips beneath characters printed in visible ink. An inkjet printer head incorporating the flexible media magnetic printing system is further provided.
