But as chips become denser, optical technologies have less of an advantage.

Meanwhile, researchers are trying to find ways to extend the boundaries of present optical technology.

This is where the optical technology really pays off.

The switches that route the information are not based on optical technology, but instead use electrical components.

Now, the race between magnetic and optical technologies is on.

For mice, the biggest breakthrough came several years back with the integration of optical technology.

Innovative optical technology makes a 26-inch display appear to be about six feet away.

Seek times and transfer rates vary depending upon the optical technology.

It may include using other techniques such as acoustic, infrared, and optical technologies.

It will combine magnetic and optical technology and cost $20.
