System Apex heeft een artikeltje in elkaar gedraaid over de True-X technologie van Zen Research, die in Kenwood CD-ROM drives gebruikt wordt en een constante rotatiesnelheid mogelijk maakt:
As these CAV drives progressed, they became faster and faster due to higher speed motors. This became another problem within itself though, as once you hit 40x max or so, the drive must do 10,000 RPM to read at that speed. This causes the “Jet Engine” effect that a lot of high speed CD-ROM owners can tell you about. It also meant that a CAV drive had to spin up to 10,000 RPM before reading, and that takes a good amount of time too.
The solution for this problem seemed to be non-existent for a time, then a little known company called Zen research changed all that. They took the trusty CLV technology, and adding something to it, and built a TrueX drive. This thing they added was the ability for the drive to emit 7 beams at once, therefore giving a 7x increase in speed, that was sustainable due to CLV technology.
This drive then hit the market as the Kenwood Multibeam 40x CD-ROM drive. While it was overlooked in the beginning, the drives soon got a small, but loyal following. That's when the word hit the streets, and the word TrueX became part of everyone's system recommendations.
The TrueX speed boost itself was not in vain either, as other things came out from it. First, the random access times were extremely low due to the less time needed to spin-up for the drive. It was also a rather quiet drive to due its low RPM speeds. But alas, it had a few bugs in the beginning though.
