3-D optical data storage technology is one of the modern methods of storing large volumes of data. This paper, discusses in details the fundamentals of 3D optical data storage. This includes the features of the 3D optical data storage and the major components that make up the devices. Nonresonant Multiphoton, Sequential multiphoton absorption, microholography and data recording are some of the writing methods used in the 3D optical data storage. The major challenges that are facing these devices as discussed in the paper are; media sensitivity, Thermodynamic stability and destructive reading.
