the potential for holographic data storage

With holotechnology information storage, entire pages of information may be saved as interference configurations. Many of these holographic patterns can be overlapping in the same photosensitive media by altering the angle or wave phase of the laser used to record them in the recordable media. In order to retrieve a page of data that has been saved as a holographic image in a holodisk, one needs to focus a laser into the disk with identical angle and wavelength as the source reference ray used to form the page. To access different pages of information, the laser is shone on the disk at varying angles. However, unlike CDs and DVDs, this does not mean that the laser must move. The angle of the laser beam in the holotechnology drive (Holodrive) may be reflected off of a reflective panel compared to be readily moved. This decreases the extent of mechanical motion and inertia in holodrives vs. traditional disk drives. Furthermore, unlike CDs and DVDs, holodisks do not have to spin in order for the drive to read them. Sub-page Vishal Holo Solutions covers additional related topics.

Some possible shapes for holographic information media include holotechnology media disks ("holodisks") and cubes ("holocubes"). The recordable media must be accessible to light, but also solid in construction. Modest-sized holographic disks or holographic cubes may hold more than a terabyte of data. When holographic storage media can just be recorded a single time, it is holographic read-only memory ("holoROM"). When holotechnology media may be frequently accessed and written right away, then it can serve as holotechnology random access memory ("holoram"). Also read Virtual Tickets .
