Latest Patents

One of her latest patents is focused on bias techniques for magnetic tape media. This invention describes a method for creating a remnant magnetization on a magnetic tape medium. The process begins with the magnetic tape being substantially demagnetized by an erasure unit equipped with multiple magnetic elements of alternating polarity. After this, the erased magnetic tape is passed by a bias magnet that generates a remnant magnetization. This remnant magnetized tape is then processed through a servo write head that writes servo patterns onto it. The bias magnet can be housed within the erasure unit or a separate bias unit, with adjustable distance to achieve the desired remnant magnetization. The remnant magnetization can exceed 20 percent, which helps to minimize defects in the servo patterns written to the magnetic tape.
