If we look back in time, we will realize that most of us used CD-ROMs as a method of storing information for quite a long time. In today's times, CD-ROMs are no longer fashionable. Due to technological development, we now use Google Drive, USB sticks, or other data storage methods. But, if you didn't know, a Romanian scientist invented the Hyper CD-ROM.
Why is Eugene Pavel famous?
Dr. Phys. Eugen Pavel, from the Institute of Atomic Physics in Magurele, made a CD (Compact Disk), made of glass, with a 15000 times more storage capacity compared to a regular one.
In November 1999, his invention was awarded the gold medal at the "Brussels Europa" World Invention Fair. In the same year, the author wanted at any cost the serial production of this CD in Romania.
He graduated from the Faculty of Physics of the University of Bucharest in 1976 (Department of Solid State Physics), as head of promotion. In 1992 he obtained the title of Doctor in Condensed Matter Physics at the Institute of Atomic Physics, with the paper "The catalytic effect of metallic inclusions in synthetic diamond technology", and in 1997 he was nominated in "Who's Who in the World".
Over time, he has been awarded numerous prizes, such as the Romanian Academy Prize, in 1991, the gold medal at Eureka - 1999 (World Inventions Fair "Brussels-Europe"), the Prize of the World Periodical Press Organization, "Kent Premium Lights Annual Awards for Innovation", gold medal at the Salon of Inventions in Geneva 2004. He has over 40 scientific works published and presented at specialized conferences, 62 patents and applications for invention patents.
In 2000, the National Technical Museum awarded him the "Prof. Eng. Dimitrie Leonida", for outstanding achievements in the field of optical memory media. In 2000, the American company "Constellation 3D" announced the creation of a similar optical memory media, under the name "Fluorescent Multilayer Disc".
Why do we like Eugen Pavel?
He is the creator of the technology for manufacturing a special fluorescent and photosensitive glass. In 2004 he founded the company Storex Technologies where, together with 4 collaborators, they work on perfecting the registration system. He is known as the inventor of the Hyper CD-ROM, with a storage capacity of over 10000 Gigabytes.
Awards and patents in the USA, Canada and Israel followed. In November 1999, his invention was awarded the gold medal at the "Brussels Europa" World Invention Exhibition.
Regarding the Hyper CD-ROM technology, it has 4 patents:
- Photosensitive fluorescent materials with three-dimensional optical memory capacity;
- The writing/reading system adapted to the existing installations (confocal microscope);
- Memory technology;
- The multiplication process.
Company Storex Technologies carried out in-depth research activities in the field of photosensitive glass and ceramics. The researcher made disks the size of a CD-ROM, with a capacity that can exceed 1000000 GB (1 PB- petabyte), the technology uses low power lasers and optical elements currently on the market.
This type of glass can store three-dimensional information — including vertically. Hyper CD withstands 550 degrees Celsius, the lifespan is 5000 years. The optical system was taken over by Sony and applied to the system called Blu-Ray.
Technical features Hyper CD-ROM (Petabyte Optical Disc)
The disc has a height of 10 mm and a diameter of 120 mm and can be manufactured using current technology.
Disk storage capacity is over 10.000 gigabytes (Go), data storage is done on 10.000 different levels inside a glass disk.
Capacity: 10 To (terabytes), with the theoretical possibility of expansion to 100 To or 1 Po (petabyte);
Average transfer rate: 3Mo/s (can be increased);
Dimensions of the CD-ROM reader: 80x150x300mm;
CD-ROM dimensions: 10mm x ø120mm;
Temperature resistance: up to 550°C;
Very high reliability;
Duration of use: (approx 5.000 years).
