The US government sometimes funds research in private companies. But there has been disagreement about the type of research that should receive public money. A consensus may be beginning to emerge.

Scientists and engineers at Calimetrics, a small company in Emeryville, California, working with Energy Conversion Devices and the Polaroid Corporation in the National Storage Industry Consortium, have developed a way of storing data on a CD-ROM disk that holds ten times more information than normal, with five times the access rate. Called 'pit depth modulation', the technique stores 8 to 16 bits of information in each pit pressed into a CD-ROM, instead of the usual two bits stored in a binary system of coding.
