CDR, CDRW (burnt cd's) wear out the cd player laser faster than normal cd's ?

Fact or Fiction ? Why ?

I ask cuz I wanna save my Alpine 7909 from premature wear. :D

heres a duscussion I found on the subject.

I read on some sites that the laser will wear out quicker...
Thats why I posed a question ..

I guess no one really knows..

The only way to know is to take 2 of your cd player that have the same usage on them and pla them the same amount of times on the same electrical system.
Unless you think someone has done that.
It's not likely.

It wouldnt hurt the laser, but it might work the error correction circuits a little more.

Even then, every laser will probably be a little different.

NO.. I never get error message on the display. I use quality cdr's (maxell) and burn them at 16x. :)
I also read that the older 1995-1999 Alpines cd players dont read cdr's very well though.

btw, the video I posted is playing cdr. :)

It wouldnt be an error message.

All CD players have an error correction circuit built into the control chips on the laser tracking system that reads then re-reads the disc to ensure it reproduces exactly what the disc has on it.

Thats why CD players can play scratched discs


Potentially a burned disc could be considered by the error correction circuit as needing more correction to the digital output that is being sent to the D/A converter in much the same way as a scratched disc.

In any case, it wont add wear to the laser itself.

Very good Rich B. Thanks..
Wouldnt it be the same for an original disc too ?

Arent CDRWs thicker than a normal cd? I thought that was why some cd players couldnt play CDRW

I just thought it was if they weren't finalized that some players won't play them. Not sure.

Regardless of what a burned disc does to your deck you are NOT going to know the difference in life span. If it goes out less than a year from now you still couldn't really attribute it to CDRs. Weird thing about lasers is that you NEVER know when they're all the sudden not be able to track. It's just the way it is. Especially with a deck that old.

I had this reply from another forum:

yes. it is true.burnt cd's read harder.their for burning out the EYE faster.its how it reads the stream lines.
i do allot of DVD burning and its cost me a ps2.and a few head units over the years.

worst problem now is that most head units continue to play the cd even if your listening to the radio.DONT keep cd/dvd's in the player at all times.

PS.buring a cd/dvd at full speed will result in glitches and jumpy play back.this is easily noticed with video burning.
a 16x burnable is best to be burned at 8x to 12x.

I have to respectfully call bullshit on this. Everyone knows that using your PS2 for a DVD player AND gaming console would shorten the life of your PS2. But to say it was from BURNED DVDs is ridiculous. It sounds to me he should have bought a dedicated DVD player and that he had some bad luck with head units.

Now this, I totally agree with. Why would anyone burn something faster and sacrifice quality? I don't. I burn as slow as I can.


My advice to you is keep burning your CDRs as slow as possible to ensure accuracy and quality.

That may be so but that doesn't mean they're all 100% in quality. Bad lasers could easily make it off the assembly floor and into consumer electronics.

Interesting. I have the Denon dual well Cd player/recorder and it burns at 1x or 2x. However, it won't recognizie the newer CDR media as recordable discs. That is except for Mobile Fidelity CDRs which are 2-12x media.

... really...?
REALLY?

I'm not going to take anything anyone says who can't use "they're, there, their" properly. Burnt CDs do make the laser re-track more... but that's about it. It's not going to damage the laser noticeably... If anything, it damages the motor more.

RSDs makes it look like it's part of the name, hence I use the apostrophe to separate the model name from the plural.

Nice try, though.
