Future High-Capacity Storage Media
One of our readers pointed me to the C3D Storage Technology web site to read about some interesting new products coming to market in the next twelve months.
FMD ROM (Read Only Memory) Disk
- This disk takes the CD-ROM & DVD-ROM concept and takes it to the next level. The planned initial production model is a 120mm 10-layer disc with 140 Gigabyte capacity - vs. less than 18 Gigabytes for a maximum capacity DVD - giving it the capacity to store up to 20 hours of compressed HDTV film viewing.
FMD Microm WORM (Write Once Read Many) Disk
- The disc is a compact version of the FMD ROM, which enables the user to select information to be stored. The planned initial production model is a 30mm 10-layer disc with 4 Gigabyte capacity. It is designed to fit into devices such as laptop and hand-held computers, digital cameras, and video recorders and players, for which it will offer lightweight, high capacity storage and quick access to data. For cameras and video players, Microm WORM will not only offer the same gains as for laptop and hand-held computers but also offer higher quality video.
- The planned initial production model is a credit card-sized ClearCard-ROM with up to 20 layers, 400 MB/cm2 data density and up to 10GB capacity - i.e. twice current single-sided DVD capacity, but at a fraction of the cost and size.
- This is a development of the ClearCard ROM, which enables the user to select information to be stored. Writing and reading are performed using a powerful semiconductor pulse laser. The planned initial production model is a credit card-sized ClearCard-WORM with up to 10 layers and up to 1GB capacity.
