The technology is similar to
FMD discs. The bit of data being held as a change in fluorescence characteristics once irradiated with one or two lasers. The target is irradiated with a pulse of laser(s) then a
CCD or
photodiode
A photodiode is a light-sensitive semiconductor diode. It produces current when it absorbs photons.
The package of a photodiode allows light (or infrared or ultraviolet radiation, or X-rays) to reach the sensitive part of the device. The packag ...

Fluorescence
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, tha ...
effect (bit value set to "1" if emitted, else "0").
Characteristics
The disc has a height of 1.2 mm and a diameter of 120 mm and can be produced with existing technology. The storage capacity of one such disk is as storage occurs on levels layered inside the glass body of the disk.
It uses fluorescent photosensitive material (glass enhanced with rare earth or vitroceramic enhanced with photosensitizing metals) as storage medium.
