TeraDisk - 1 Terrabyte Optical Disk

By admin • March 8, 2008

What’s better than the blu ray disc? Well there are a few out there that are pretty good and hold as much or more space. One is called TeraDisk.

Using a red laser on Mempile’s current media, the TeraDisc can record 200 DVD-like virtual layers resulting in close to 1 TB of data. With the refinements expected over time, the number of data layers will be substantially increased and other attributes like mark size and spacing decreased. Capacities of 5 TB can be expected.

Drive Components include:

CD-like system for tracking
Red read/write modelocked picosecond laser
Sensitive detector for read signal (450-600 nm)
Two dichroic elements
Focus offset control (to pick the desired working layer)
Independent servo systems for the tracking and read/write lasers
Variable spherical aberration correction

I hope things start to speed within the computing industry because we have these same old CPU’s and motherboards that are around the same speed as before. I want the industry to make massive improvements in speed and storage.
