Researchers at Purdue University have developed a technology that aims to replace Morse code with colored “digital characters,” helping to modernize optical storage media. The advancement, the researchers said, will help with the expansion of remote data storage during and after the COVID-19 pandemic.
Rather than using the dots and dashes of Morse code, the researchers’ approach encodes information in the angular positions of tiny antennas, which allows them to store higher amounts of data per unit area.
“The storage capacity greatly increases because it is only defined by the resolution of the sensor by which you can determine the angular positions of antennas,” said Alexander Kildishev, associate…READ MORE
