ON THE HORIZON Scientists, computer engineers, and entrepreneurs of all kinds are working to develop new and improved hardware devices that will make information access faster and easier. After all, much is at stake—the millions and billions of dollars in revenue to be shared by successful individuals and companies. Inventors are also motivated by the great satisfaction that comes with creating something new and better. Increased Optical Disk Storage Capacity Computer users needing huge storage capacities may be pleased with a new type of optical disk storage called FMD-ROM. A Fluorescent Multi-Layer Disk (FMD) holds up to 140 gigabytes (GB) of data. This capacity is currently 215 times greater than a CD-ROM (0.65 GB) and 23 times greater than a DVD-ROM (6 GB). FMD-ROM disks contain fluorescent materials embedded in the pits and grooves of all 10 or more layers. The fluorescent materials are stimulated to produce coherent and incoherent light when in contact with a laser. Data is stored in the incoherent light. Because the technology is not based on reflection, multiple layers are read at the same time.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
