Norsam, IBM team to read data on 165Gb, CD-sized Disks

IBM's research arm has teamed up with Norsam Technologies to develop techniques for reading data on high-density storage systems, which can store up to 165Gb of data on a CD-Rom-like disk. Through a technology transfer program with the Los Alamos National Laboratory, Norsam has developed a disk called the Norsam HD-ROM, which it says can store several hundreds times more data than a traditional CD-ROM. IBM and Norsam will work together to develop methods for accessing data on the Norsam HD-ROM discs, according to a company statement.

IBM's research arm has teamed up with Norsam Technologies to develop techniques for reading data on high-density storage systems, which can store up to 165Gb of data on a CD-Rom-like disk.

Through a technology transfer program with the Los Alamos National Laboratory, Norsam has developed a disk called the Norsam HD-ROM, which it says can store several hundreds times more data than a traditional CD-ROM. IBM and Norsam will work together to develop methods for accessing data on the Norsam HD-ROM discs, according to a company statement.

Specifically, Norsam researchers will work with IBM scientists Dr. Kumar Wickramasinghe and Dr. Yves Martin of IBM's T.J. Watson Research Center in Yorktown Heights, New York. The team will study ways to enable IBM's Scanning Interferometric Apertureless Microscopy (SIAM) technology to read Norsam's HD-ROM high-density disks, Norsam said. Norsam has a data-writing technology for the disks in place, but hasn't developed a device to read the disks.

Norsam's disks use a charged particle beam for data writing, allowing up to 165Gb of data to be stored on a CD-sized disk. In comparison, CD-Romand DVD-Rom disks are written using laser beams, enabling capacities of between .65 and 4.7Gb.
