Lesson plan
Hyper CD-ROM
The Hyper CD-ROM is a claimed optical data storage device similar to the CD-ROM with a multilayer 3D structure, invented by Romanian scientist Eugen Pavel. The technology is supposedly 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 wait for an emitted light by the medium due to the fluorescence effect (bit value set to "1" if emitted, else "0").
