The Hyper CD-ROM is a tridimensional multilayer optical memory, based on the phenomenon of controlled extinction of the fluorescence.
The Hyper CD-ROM allows the recording of information inside the “shelves” of a glass disk using laser beams. Such a glass disk has a storing capacity of over 10,000 Gigabytes (GB) of memory - an amazing size in comparison with those developed by the highest level computer firms and benchmarks - that allows storing of approximately 10 million books of standard format. It is in fact, an “optic tridimensional multilevel memory” so it can store data in over 10,000 different levels inside a glass disk 10 mm high and 120 mm in diameter. The most attractive aspect is that the support for storage (i.e. fluorescent photosensitive glass) is a very stable in time medium (information can be read during all the life of the glass - estimated to at least 5,000 years).
Capacity: 10TB with extension to 100TB
The product can be produced using commercial equipment
The support of the optical memory is a fluorescent photosensitive material specially designed for this application.
The writing / reading of the memory is realized with a system
formed by a disk drive having the size doubled compared to the usual disk
drives of the desktops PC, which incorporates a confocal microscope. The
writing procedure is realized by the irradiation of a selected volume of
the optical memory. Following the radiation, there appears an electronic
transition at atomic level, and the irradiated areas will present a
modified fluorescence compared to the non-irradiated areas.
Due to the fact that in 1micron^3 of fluorescent photosensitive material there are approximately 10^8 fluorescent atoms, the improvement of the techniques for three-dimensional limiting of the atoms, will allow the increase of the storage capacity up to one hundred million times. The writing and reading on groups of atoms located in equivalent positions will allow the increase of storage of more than 100 times, which means that on a disk with a 120 mm diameter and 10 mm thick more than 1 PB (1,000,000 GB) can be stored.
The need - Estimations regarding the necessary storage capacity
As presented by Constellation 3D at a demonstration in Silicon
Valley on 30 November 1999, quote “the growth in demand for digital
storage capacity exceeds 60% per annum, with no indication of a let up in
the trend. Facilities such as Storage Area Networks, data warehouses,
supercomputers and e-commerce related data mining require ever-greater
capacity in order to handle the volume of data to be processed.
Initially, the 3D optical memory was developed for military

The Hyper CD-ROM technology is patented in 21 countries: USA, Canada, Japan, Israel and 17 European states. The Hyper CD-ROM, presented in November 1999 at Brussels EUREKA “48th World Exhibition of Innovation and New Technology”, won “Prix International de l’Organisation Mondiale de la Presse Periodique” and a gold medal, and in Romania, the Grand Prize of the “Kent Premium Lights Annual Awards for Innovation” 2000 organised by the Romanian Design Foundation.
