Being from the
Semiconductor Industry, I spend time with a lot of Electrical
Engineers every day. Most are fairly intelligent folks. When I have
the occasion to meet with Optical Engineers, I am usually blown away
by their brilliance. These folks deal in almost a sort of
"black magic". It is truly "deep" stuff. We'll
spare you the physics here folks and keep things crisp. In short,
what you see in the above diagram is the way the 72X True X CD-ROM
Drive's Lasers are split into to seven discrete beams and track
across the disk. This allows for 7 parallel reads on a rotation and
thus incremental gains in throughput.
The "7 beam
pick-up" as Kenwood calls it, is a patented technological
for a closer look...
It also allows
for lower disk rotation speeds as a result. This drive is one of the
quietest drives I have ever tested, period. It is as quiet as most
4X drives so long as you have it mounted correctly so there is no
rattle in the case around it.
