I referenced my own feedback from attendance at the SH meeting. siliconinvestor.com You said: "This sounds like Calimetrics PDM technology to me. Believe PDM stands for Pit Depth Modulation" The above sounds completely different to ECD's technology which is a 'phase-change' of chalcogenide material with power (electrical or optical) input. For optical purposes the phase-change corresponds to a change in the refractive index of the material and hence a change in the reflectivity of the material. Looking for other ECD references to use of this for optical storage. Ed
