The Road to Multi-Dimensional Bit-by-Bit Optical Data Storage

Min Gu and Xiangping Li

Recent advances in optical data storage have led to the development of a five-dimensional device that could hold up to 2,000 times more data than a conventional DVD.



Optical data storage has led to revolutionary advances in information technology and storage. One of the challenges in this field is to meet the rapid growth in demand for storage capacity. Bit-by-bit optical data storage systems such as compact discs (CDs), digital video discs (DVDs) and Blu-ray discs (Blu-rays) have emerged as compact, portable devices that have high memory density and high resistance to intense electromagnetic radiation. Given its high tolerance to vibration and robust reliability, bit-by-bit optical storage has been shown to be superior to holographic memory.
