Posted: May 13, 2000 Written by: Tuan "Solace" Nguyen LIMDOW What the heck is LIMDOW technology? Well, LIMDOW stands for Light Intensity Modulation Direct OverWrite -- (what the hyolios?!). It is derived from MO technology. Traditional MO technology requires that the disc be rotated twice in order for information to record. With LIMDOW media, the disc need only be rotated once. The drive records data by heating areas of the disk to their "Curie" point, as with regular MO media. However, depending on the write laser intensity, the magnetic element orients itself with either the external magnetic field or with a reference layer that is built into the disk, sitting above the elemental write layer.. Because of this, data can be written in a single pass. Conclusion And there you have it, the repertoire of optical storage technology. I hope this article has shined some light (pardon the corny pun) on how optical storage works. But, I did intentionally leave out another optical storage technology -- holographic storage. I’ll be discussing this amazing technology in-depth next time. Be on the lookout. Until next time... *Thanks to Ken C. Pohlmann, Professor of Music Engineering Technology, University of Miami.
