Using CDR's in a standard head unit or changer will kill the laser very quickly. Only play original cd's or lose the cd player altogether, choice is yours ;) :y

I was hoping someone would ask that question, considering the laser head never actually touches the CD  :-/

Put very simply  ... a "purchased" CD is "stamped" from a sheet of foil... and the working surface (the rear of the "label") is a mixture of highs and lows... with an actual physical difference existing... albeit very small ......

A "burned" CD (home made) the "foil" has a dye within the surface, when "burned" the dye is heated to change colour and gives the impression to the laser that the surface is at differing heights, so fooling it into giving the same output as the real highs and lows of the stamped disc.

The problem is .. the laser "knows" it needs to change the focus to get the high and low in focus every time .. but the "dyed" disc is all at the same distance .. so the focus mechanism of the laser is working overtime to achieve very little ... it thus wears out much faster....

Perhaps not totally accurate but gives the basic idea hopefuly

Certainly accurate enough to give me a reason for not using recordables in the car.
Your reply also prompted me to investigate a little further and all I could find to add was that
'recordables are optimized for use with the lasers in computer optical drives'. Explaining why some recordables just won't play.

Many Thanks   :y

so does this apply to stereos manufactured to play mp3 formats also? as i have just installed a unit on this basis alone burn all my music to a pair of dvds and let it play or am i risking the same problem?

Generally, MP3 players are OK with CDRs. Still use quality media (Verbatim or TY) and use a slow speed and a quality CD Writer.

I believe .. but have no proof  - perhaps Dave DND with his expert knowledge can help - that "newer" CD units use a different focusing system that is able to handle "home made" discs far better.

You have to remember that the technology in Omega systems is well over 10 years old ... "CD-R" hardly existed then ... things move on in the technology world at ferocious pace !!!

Any CD or DVD that I burn that I want to play on a CD or DVD player (ie not a computer drive) I burn at the slowest speed that my CD/DVD burner will support.

Audio CDs burnt that way seemed to play more reliably in my CDR2006 than pressed ones (until I read about why I shouldn't  ::) )

It does actually say cdr's are not supported in the manual.
