Optical disk pickup using current mode signal exchanges and systems and methods using the same

Ser. No. 09/282,849, entitled "SERVO CONTROL LOOPS UTILIZING DELTA-SIGMA ANALOG TO DIGITAL CONVERTERS AND SYSTEMS AND METHODS USING THE SAME" filed Mar. 31, 1999, currently pending. An optical disk pickup system includes an array of photodiodes for converting photons reflected from an optical disk into a plurality of electrical signals each representing a channel. Driving circuitry drives at least one of the electrical signals as a current across a conductor of a flexible cable . A low impedance load converts the electrical signal driven across the conductor as a current into a voltage for further processing.
