Motion profiling during acceleration and deceleration is designed to better utilize available torque provided by the motor in order to quickly position the medium during start-stop operations and to reduce the maximum power or speed required of the motor during the indexing operations. In particular the present compounds have physiochemical properties that facilitate penetration of the nail plate. A metallic layer is formed on the card by plating. Such a system and method is especially useful for utilizing audio, video, telephonic, andor other functions in multi-function electronic devices utilizing both monaural and binaural audio.
