Abstract
We report a new magnetic MEMS technology that enables many electromagnetic MEMS devices. This new technology combines magnetic thin films and silicon bulk micromachining. Its use is demonstrated by two types of millimeter-sized analog scanning mirrors that are capable of delivering deflection angles exceeding 60 deg. Details include the design, fabrication, operation, as well as a complete electromechanical model of the mirrors. In addition, the use of the mirrors is further manifested in a holographic data storage system where hundreds of holograms have been successfully stored and retrieved.
