Latest Patents

Sander holds a patent for a "Method and apparatus for retracting head and braking motor of a disc." This invention addresses the need for improved safety and efficiency in disc drive devices. The head assembly of a disc drive device is retracted upon the interruption of power to that device by utilizing the electromotive force generated by the disc drive spindle motor. This occurs as a result of the rotation of that motor following power interruption. After a sufficient delay to allow the head assembly time to retract, the spindle motor is dynamically braked. Dynamic braking is achieved by utilizing a voltage to which a capacitor has been charged during normal operation to energize switching elements that effectively short circuit the motor windings.
