I have been cleaning out the attic and found an original Technical Training notebook. It is is very good clean conditions. I am also disposing of RCA laboratory notebooks that dealt with the carbon ...

I am cleaning out my real old files and found the original Dr. Pab Datta quarterly report 1979. Pab (inventor of the VideoDisc) used to complain to me that his first report on the videodisc was class ...

I guess so far I am the oldest at 63. I help Pab Datta formula the CED at RCA, Princeton. Funny, I was one of the youngest on the team.

A friend call me from the lab and told me that Ron retired to Florida. I will reach out to him and see if he is interested. Roughly, the disc without silicone oil was coated with chrome. A laser t ...

I posted a photo of the inhouse RCA journals on VideoDisc and a scale model of the stylus and disc. http://vual.net/VideoDisc.html

This may sound like a very simple answer to a dirty stylus. Remove the stylus and touch the tip gently with scotch tape. We used this method in the RCA lab to kept the diamonds clean.

I worked at Sarnoff in Princeton doing formulation & testing of the disc. I spent a lot of time in Indianapolis at the plant.

The early CED had problem with a contamination in the carbon black which makes the plastic conductive. This contamination was eliminated that would cause the disc to age.

Don't take the disc out of ...

I am a former RCA scientist on the VideoDisc project involved directly with the factory and research in Princeton,NJ. Because of space requirements I am looking to disposed of 981+ titles, a number o ...

You may want to try scotch tap carefully on the end of the stylus. We found that it remove debris very well and regenerated a stylus in many cases.
