why does this happen?

I have an HHB CDR 800 recorder/player. I have ten cd's that when inserted the player responds with a "no Disc" message. If I then COPY the cd to a CDR on my computer and take the burned copy of the same CD....it plays in the HHB. I hope someone knows the answer to this, it just bothers me. The CD's that wont play were bought new by me and not owned by anyone else.

Do they have the Compact Audio Disc logo on them. There was an incident a few years back were phillips (Cd's primary patent holder) found out the record labels were modifying the red book format to incorporate copy protection and thus made the disc's incompatible with some players. Since Red Book has no DRM, phillips demanded that they remove the Compact Disc logo and place a warning on them saying the may not be compatible with all players. Also before anyone points it out I do realize you copied them, even with DRM it's possible to make a copy. Especially when you use DRM that windows media player can bypass.

these are regular CD's with the logo on them. These discs play in other players I have, its just that I have to burn a copy to get it to play in the HHB.

There are probably a couple of possibilities. It could be that the CDs in question are abnormally less reflective than most CDs, and it could be that your recorder isn't very good at dealing with that issue. Or it could be an issue with the table of contents (data) on the CDs, that is different in a way that your recorder can't recognize.

There is the possibility mentioned by Vintage_Hi-F, as companies did release albums improperly before Philips cracked down on them for releasing nonstandard discs with the CD logo on them.

Here you can see an old article on the subject:

Keep in mind, what they were doing then is not the same as what they are doing now. But you could easily have copy protected discs without knowing it.

I had a similar problem with TDK music CD-Rs recorded on my Pioneer PDR-555RW.
They use to play in my old Kenwood DP700 cd player fine.

I believe they changed the formulation. The batch stamp on the CDs were a different font. The TOC finalization time also changed.

The new batch could not be read by the Kenwood. But they played ok on my Sony's. So whether reflectivity or structure, I don't know, they played fine on the recorder but not on all other CD players.

The old batches played fine on everything.

So also I tried making a I copy of one of the new batch music CD-Rs to a data CD-R on my PC and that played ok on the Kenwood.
