Researchers explore alternative recording systems using light and microscopic dots and dashes.
From clay tablets to magnetic tape, civilizations have found ways to store important information; however, the silicon revolution has led to an overabundance of data. While existing electronic media have kept pace with this demand, new technologies could offer massive storage coupled with fast retrieval.
Scientists are exploring new systems that could become commercially available in the coming decades while continuing work on improving the capabilities of existing media. Some of these techniques, such as light-based memory, may open new paths for high-speed computing, experts say.
