Question

Quizplus · Accepted Answer

Holographic storage devices store information in a three-dimensional volume, not a two-dimensional surface. They use lasers to create holographic images or three-dimensional patterns within a crystal or other storage medium. This allows for much greater storage capacity and data transfer rates compared to traditional two-dimensional storage mediums like CDs or DVDs.
