It's lubrication for the needle.  It's a non-evaporative silicone coat that's
supposed to help extend the life of the stylus.  A disc may play without this
coating, but wearout of the stylus may be accelerated.  - Reinhart

I have used Dave's method of cleaning discs of all types; LPs, CDs, DVDs, CEDs
and ROM discs of all kinds.  It is the best method I know of.  However, just
air drying after a good, mild wash is less potentially distructive to the
surface of the disc.

================================
   i suppose that is a good idea after you have tried fast scan etc,to a
disc that refuses to play.  
   
 according to RCA  removing the protective  coating  increases friction
between the stylus and the disc itself. thats why its there.(the reading
speed is 450 rpm)
      so if washing the disc was successful, i would copy to vhs and not
use the disc again. stylus' are too expensive to take a chance.

Reinhart,
 
Thanks for the information.  It was very descriptive and helped me to get the
disc and spine out of two of my Radio Shack players.  I have ordered some load
belts from Tom's website to fix these machines.  Other than have a problem
unloading they work perfectly.  Again thanks very much for the assistance.

Before taking the trouble and risk of cleaning CED VideoDiscs please read
on -   I have seen players where the picture was degraded with streaky
lines.  The player owners had reasonably enough supposed that their
videodiscs had seen too much use and should be cleaned or replaced.
Actually the cause of the problem was a malfunctioning defect correction
circuit in the player.  I all cases I have seen, the problem is fixed by
replacing the Comb Filter/ Defect Corrector I.C.   Not a difficult task for
those who know the player well enough the remove the master printed circuit
board.  The I.C. is available for RCA CED players as RCA part 149039.

Subject: Gerard Alphonse Wins IEEE Election
To: digest@cedmagic.com

Hello All:

I'm happy to report that CED scientist Dr. Gerard Alphonse won the election to
be president-elect of IEEE-USA. He will perform that role in 2004 and assume
the presidency on January 1, 2005.

http://www.cedmagic.com/mem/whos-who/alphonse-gerard.html

Dr. Alphonse wrote two articles on CED mastering that appeared in the March
1982 issue of _RCA Review_ "Power Dissipation in Piezoelectric
Cutterheads" and "A Method for the Characterization of Piezoelectric
VideoDisc Recording Heads Using a Bridge Circuit."

You may be able to find archives of the technical journal _RCA Review_ in the
libraries of universities that have a school of engineering. The March 1978,
September 1978, and March 1982 issues are entirely devoted to CED, while the
September 1981 issue has three articles on CED and a cool photo of a stylus tip
on the cover.
