In businesses around the globe, there is an immediate need for cost-effective, high-speed, large-capacity tape storage that can reliably back up large-scale network servers and handle huge volumes of images and other storage-intensive data. To meet this growing business demand, Sony has unveiled new standards in tape storage technology. The Advanced Intelligent Tape (AIT) format is Sony's latest innovation in fast access, high-density tape recording technology and forms the basis of Sony's new SDX series of tape drives and media.
