There's always an exception, but I would first check NDM out then ask Esoteric. Hard to imagine not being able to use NDM unless you have a slot load player
"Tuning" CD's
Shaving Compact Discs to improve the sound (?!)
This Youtube will trigger the usual chorus of self-appointed audio rationalists, but I have a much simpler workaround that involves simply sanding the edge of the CD and then blackening the edge of the CD with a magic marker - all in the service of nullifying incident laser reflections bouncing off the glossy edges of CD's.
The results were so impressive that I now perform this procedure on all of my CD's. I should add that my system plays CD's only which are burned from downloaded flac files. The files are converted to .wav files in JRiver and burned at the slowest speed my desktop drive can achieve.
Please let us know what the you hear or do not hear.
I should also point out that the sonic graphs displayed the the Youtuber for comparison between the treated and untreated CD's are not symmetrical if you look closely.

Yep, they were a thing.
Audio Prisim StopLight pens. I still have a couple.

@bolong "blackening the edge of the CD with a magic marker - all in the service of nullifying incident laser reflections bouncing off the glossy edges of CD's." New Dark Matter "The color black is ineffective for absorbing infrared light; for CDs black is effective only (rpt only) for the inner edge. When black is used for the CD outer edge or the CD label it hurts the sound" Guess one of you is wrong.

It occurred to me last night that simply sanding (i.e. frosting) the CD edge should be plenty sufficient to stop reflections. No paint or marker necessary. Since I am a furniture maker and have the requisite tools in my shop it shouldn't be difficult to make a CD edge sanding setup on my lathe thus speeding up the process and allowing for batch processing. 100 grit "coated" paper (to reduce grit contamination) is what I have been using. It is available from all the box stores or Amazon. |
The plot thickens. Lesson Explainer - Infrared Radiation "In the other direction, rough surfaces such as fabric or cloth will not reflect IR well, instead absorbing it nicely." "An object with strong reflectivity will reflect more IR, meaning it must be weakly reflecting to absorb more IR." "Besides color, the second factor affecting how much IR is absorbed or emitted is the reflectivity of a surface. A highly reflective or glossy material, such as cut obsidian, will poorly absorb and emit IR, even though it may be a deep black color."
