Ooopsies.. CD Shatters in my burner.. Advice? **Now With Pics**

[screw3d]

There was once my friend's CD flew right out of the drive and hit him square in his forehead like a frigging frisbee. It was some cheapass no-name drive though. Pretty hilarious.

If it works, then you're ok. If it doesn't you're screwed.

Since it was a regular CD you should be OK. If it was a CD-R, it's a different story though. A CD-R spreads out millions of conductive silver confetti everywhere when it breaks and it can cause electrical problems inside the drive.

maybe you're thinking of a cd/rw.. cause a cdr is just like a cd...

Except for that whole, you know, ability to write to them by commercial laser products and not industrial stamping machines ... yeah, totally identical.

oh, fine, nm. i make a stupid comment, i only need 1 person to point it out, not 5, thank you.


i had figured that because a cdrw was rewritable, it would use a vastly different type of "burning".

i had figured that a cdr "burns" by focusing a laser into a piece of plastic and thus, the plastic undergoes some sort of change, and becomes cloudy or something.

1 = cloudy
0 = clear.

that kind of thing.

guess i'm wrong.

Some faster drives have speed switching option where you can toggle between maximum speed and 40 or 48x.

I have no reason to be in so much hurry that I need a 52x over a 40x.

Going 52x means you gain a peak speed by 30% by increasing the rotational speed by 30%. The centrifugal force is square of the angular speed, so you put about 1.7 times as much stress on the disc relative to 40x. This explains why disc breakage can be a problem.

If I recall correctly, the spindle speed exceeds 10,000RPM at 52x.
I don't think the CD's plastic subtrate specs have been updated in a long time and they were originally engineered for audio CD which spins at about 500RPM.

At 10,000 RPM a disc is subjected to 400 times as much centrifugal force compared to when it's used in a 500RPM 1x drive.

There's no way I'd stick another good CD in that drive. If it screwed up once, it can screw up again. Buy an identical drive and return that one in it's place, with the explanation that it destroyed a CD. Make sure the serial number on the drive matches the box. You do have the box it came in, right?

The problem is that the particular CD wasn't able to withstand the centrifugal force exerted on it at 10,000RPM. It's not a very rare thing. The identical replacement drive would exert the same amount of centrifugal force on it and if a disc can't withstand the force, it will give up.

It's not a problem with the drive.

Fiberglass? You're joking, right? 😕

Whoa. Did I say that? I was looking at fiberglass insulation prices at the time...

Lord knows what they're made of, but go break one and tell me it doesn't get everywhere. AOL CDs are ncie for this type of experiment.

here's for your education. the only real difference between CD R and CD RW is more in the software than in the CD disc itself. it's how the sessions are being ended and not what happens in the process of burning that determines re writability.

oh also, you don't truly ReWrite, what you do is continue to write from where you left off, it's not like magnetic media where you write and rewrite in the same location. once you've burned to a part of the dye, that dye is no longer available to be written too again.

there is a MUCH bigger difference between CD's and CD R/CD RW's than there is between the CD R and CD RW.

Attach it to a Dremel and spin it up to 35,000RPM 😀
That would be ~180x equivalent.

 

[djheater]

the exterior circumference of the disc can't keep up with the interior. A disc with an internal fault or serious screen print variance will be more likely to fracture because of the added stress.

It'll happen. That's why we don't have faster burners yet IIRC.

wtf what causes this? thats so random

the disc is spinning at about 5200 times per minute which causes microfracturs on the cd...

or the ball bearings mess up

Yeah, I saw an article about this, there have been many instances of this happening in 52x cd-rom drives because of the speed issue. That is precisely why I will never buy one.

no, in a cd/rw, all 640 mb are available each and every time you try to write something to it. just like a fricking slow hard drive.

in a cd-r, i can write, delete, write, write, write, write some more. it's not based on how it ends, because on a data disc i never end it permanantly. i can fog up the file structure, and that is akin to deleting something. however, the space that that something used before is not available anymore. so if i wrote 20 mb to a 640 mb disc, then deleted everything on it, i'd have a 620 mb blank disc.

i guess this is why i make 1:1 backups of every disk i buy.

What if your expensive disc blows up in that process haha.

at 12x.

first burn, i burn at less than highest speed. 😛

hmmm. if so, than i have completely misunderstood this whole CD-RW thing. i've been known to be wrong before and i don't have a problem being corrected. can someone else substantiate what walleye just said?

i've done it with the built in burning suite in XP.

WTF? All this bickering over a $30 drive? $20 after rebate?

 

[Tab]

This is why you dont see many burners over 48x

i've seen that happen hundreds of times... older discs can't handle over 40x rotation

there is some education software called "Read 180" that the school use around here... it's like an 8 or 9 disc set that kids learn from. The 2nd CD is the "Disaster" cd that shows videos of volcanos and earthquakes and all kinds of bombs and stuff.

If you hold all the 8 cds together, you can see that the 2nd CD is just a bit thinner, and it would 10 times out of 10 explode inside of a 52x drive

CD/RW uses phase change dye. It can burn using one laser power level and erase using another power level. Linky
