The disc offers far more storage capacity than existing DVD-Roms, which can store up to 17Gbytes.
The 100Gbyte disc is expected to become available in 2004, when applications such as high-definition TV will create demand for larger storage capacities, said Din Ping Tsai, professor at NTU and leader of the research team.
The disc, which was developed with the backing of Taiwanese optical disc maker Ritek and Taiwan's National Science Council (NSC), is able to achieve a higher density of data and greater storage capacity than existing CDs and DVDs through the use of near-field optics.
Unlike other recent advances in optical storage that require the use of blue lasers, the 100Gbyte disc developed by the NTU team works with the read-write heads found in CD and DVD players that employ red lasers, which have a longer wavelength than blue lasers.
Near-field optics technology increases the disc's storage capacity by allowing a red laser to make recording marks smaller than its diffraction limit. These smaller marks can be spaced more closely together, increasing both storage density and capacity, according to Tsai.
To achieve this, two layers have been added to the near-field region of the recording media.
The first layer is a transparent layer, called a spacer, which is between 10 nanometres to 20 nanometres thick. The second layer, the active layer, interacts with the laser's focusing spot to create a very small mark size.
Because the interaction between the laser and the recording media takes place in the near-field region, there is no diffraction limit, according to Tsai.
The only hardware change required to accommodate the disc's higher storage capacity is an upgrade to the player's chipset that supports the smaller mark size, Tsai added.
The disc can also be used with players that do not have an upgraded chipset, though the mark size would not be as small.
Research on the near-field optical disc began in 1998 and has so far been funded to the tune of TW$30m (£598,000) by both Ritek and the NSC.
