An electro-optic modulator is driven between discrete operating points such that a reversal of applied field polarity reduces harmful charge screening effects and the voltage swing between the operating points is reduced from previously used voltage swings.

Method and apparatus for driving an electro-optic modulator assembly

An apparatus and a method for reducing cross talk in tape recording and playback systems is disclosed. A single magnetic track containing D data bytes of the prior art is divided into W substracks, each containing D/W data bytes. The tape recorder is capable of recording at a preselected full speed and integral fractions thereof. When recording is done at less than full speed, the W subtracks which comprise a track are offset longitudinally, such that the area covered by the W subtracks approximates the area of a single track of the prior art recorded at full speed. To further suppress cross talk, wide write heads and narrow read heads, or opposite azimuth angle heads may be used.
