My CD has static on last two tracks

[pinger]

Last two tracks have some type of static/scratchy noise. Verified its not the system. Does the same thing on two completely different systems. Visually disc looks fine. I believe the last two tracks would be on outer edge? Should I just try to wipe the disc with some type of soft cloth ( like those used to clean eyeglasses? ) Thoughts

We use warm water, a drop of soap and a microfiber towel to dry.

If you have a CD reader, try ripping the disc with AccurateRip: https://accuraterip.com/software.htm

If the checksum matches their database, then you know that the noise is inherent to the master and no amount of cleaning will fix it.

Is it happening on every disc or just one?
If you clean the disc, you should wipe "radial" - not like an LP.

Just this one disc. On the last two tracks only

I'll try that. Thanks

If no scratches, it's probably a "rotting" CD, alas. Can also happen with CD-R/RW:

I had it with some CDs, in my case they got multiple circular spots near the edge, only visible if held against a light bulb. The last track couldn't be played, later two tracks... If this happens, YMMV with ripping, slower ripping might still succeed, but mostly it will not. That's why it's better to rip them while they're good.

Sometimes the disc is simply defective.

Visually disc looks fine.

The data layer is on the top (label side) and it's read through the full-thickness of the polycarbonate.* The CD can be damaged from the top (perhaps more easily than the bottom shiny side) and it's often hard to see, and attempting to polish it will only further-damage it. Cleaning won't help from the top.

You might have to find a replacement CD.

Or if it's not too badly damaged and the CD in in the CUETools database you can rip and repair, and then burn a new CD if you want one (if you want the physical CD). ...I've never tried CUETools repair myself so I can't help.

Or if you can't find one, maybe buy the MP3 tracks from Amazon (if they have it) and burn a new CD (using the two MP3s for the 2 last tracks). Of course MP3 is lossy and decompressing it to PCM for the CD won't be "perfect" but it won't sound scratched.



* DVDs and Blu-Rays are different. The data layer on a DVD is in the middle of a polycarbonate sandwich. On a Blu-ray it's on the bottom with a thin "hard protective layer".

IIRC some labels will replace a "rotten" disk if a newer issue is available.

In answer to the OP's question in the initial post (which I don't believe anyone's addressed? Apologies if I am wrong about that!):
yes, CDs play from the inside out (so to speak). The rotational rate of the CD changes as a function of 'track' radius, too.
