#CD-R adjustment
7 messages in this thread
Felix,
Awhile back we had some discussions here regarding what adjustments they make
to drives to assure they read CD-R discs properly given the various
characteristics of various types of CD-R media. Can you enlighten us on what
happens when someone sends their drive in to you for this type of adjustment?

I'm willing to bet that no one's ever had to send in a Plextor drive for that
kind of adjustment… <G> Maybe we'd better ask someone else.
Best,

Unless you want to include the Texel drives (now Plextor) in that group. I
have had to had Texel drives fixed and they still don't work….no trouble with
the 4Plex however.

Make that "newer Plextor". In the Texel era it was a problem in my experience.

Maybe, but I just sent a 2 year old one in to have the laser replaced <g>

Well that's an easy one (NOT!).
In most cases there is a focus sensitivity circuit that can be adjusted on the
oscilloscope. It gives you the best ability to read as far to the left of the
track as to the right. As you might already know silver discs differ from gold
because (not only because) silver is stamped and gold is recorded. Due to this
the track is stamped on the silver (pretty uniformly) and laid down on the fly
on the gold. So, if you can imagine driving down the California coast line at
6X speed and enjoying the view or driving on a straight road. Sorry, that's
too far out there. Anyhow, what I am trying to say is gold disc is harder to
read. Most drives will not give you the same performance specs using gold disc
as they do with silver. Try it. There are other things we can play with but
they are too specific so let's just say we tune up our drives with CD-R in
mind. Hope this helps. FN.

Felix,
Very interesting, indeed. Thanks for the info.
