Abstract: A method and apparatus performs the detection of an edge of a tape and further controls the read/write head to position itself relative to the detected edge. An array of photodetectors in an integrated circuit chip senses the intensity of light illuminating the chip with the tape running between the light source and the photodetectors. A light-to-dark transition is formed which is indicative of the edge of the tape.

Abstract: An electrostatic discharge noise suppression method and system is disclosed for electronic devices, particularly those connected to data buses. Electrostatic discharge protection is provided by breaking high-frequency ground loops by inserting common mode inductors where they can be most effective-in the DC power supplies themselves, in the DC power connections, or just behind the DC connector in the electronic devices. Saturation of the cores of the common mode inductors is prevented in a preferred way by equalizing supply and return currents in the common mode inductors and by preventing DC ground currents from flowing in a chassis between the power supply and the electronic device.
