CD player vibration from CD's

Over on Audio Asylum almost same question today..
The Cd can be slightly warped. Since the machine only grips a CD bt the center hole, and no support around the rest of the disc, if the center hole is not level with the rest of the disc, (warped) the disc will cause vibrations as it rotates.
The miracle here is that the lens has to be really really close to the Cd surface to read the disc, and follows the vibrating discs perfectly. Amazing!
So, if you do not want the discs to vibrate, toss the ones that do it.
Sometimes those aftermrket 'disc stabilizeers' help with this.
Also: here is a perfect 'oppo'rtunity for some tweak genius to make a device to flatten discs that vibrate.
Or, buy a Pioneer with the inverted 'stable platter' which supports the entire disc.

If you can track it down to certain cd's that are vibrating, try them in a different player, maybe it's the Oppo that is the problem. I'm not sure a slight warp would cause a vibration, it may be more likely an off center (out of balance) disc can cause a vibration, those discs can be cut to even them out. I only own several hundred cd's but have never seen this problem, good luck tracking it down.

I experienced it with a different player, a Denon DVD player which I soon returned to the retailer. Only happened with some CDs but the same CDs played fine in a couple other CD players I owned.

leatherneck why not do what i do with warped CDs. I put it under enormous amounts of heat and pressure. These conditions will form diamonds naturally.

Hi Elizabeth

Thanks for sharing again. Your posts are often really informative to a novice like myself.

Regarding disc stabilizers. Would those a Carbon Fiber CD Mat help? What stabilizers would you recommend?

My Oppo BDP-83SE and stock BDP-83 vibrate a bit quite often regardless of disc. Be it an SACD, Blu Ray Disc, XRCD or CD. I thought the vibration was normal. I just put 2 5 lb weights and sheet of Acoustimat under the weights to help with the vibration. I'll keep doing more checks to see what discs cause the most vibrations. I'm pretty careful with my CDs. I wonder how they could have warped.

Thanks
