CD exploded

[ssahl]

This is like the 3rd time I've had this happen, a CD exploded in my CD-ROM drive, and I mean loud, exploded, POW! Is it really necessary to have a CD-ROM drive that spins at 56x or more?
This last CD I had explode didnt even have a crack in it, put it in closed the trey and POW! just like a firecracker, little tiny cd pieces everywhere, like confedie.

Wow and everyone always wants a faster computer...LOL. I think Hpro has run into that in the past...if he's around you might ask him.

This is a common problem with CD-ROM drives over 48x.

Therefore there will never be a CD-ROM drive over 56x. Those 52x and 56x CD-ROM exist for quite a while now.
But exploding CDs should only happen to CDs that aren't 100% ok, not with non-damaged CDs.

How come Kenwood makes 72x? Or something like that?

[RJ]

They weren't 72x. Although they were marketed as 72x drives they were not faster than 50x drives. And they were unreliable. Therefore they are not built anymore.

so what actually happened is the spindle lost the cd and it went irradic in the drive and got broken because it was moving so fast?

Never heard of CD actually expolding!

I have had the same problem once before. I dont know why it happened but the CDROM was a 52X. It has never happended in anything less I think it has to do with the CD quality.

BTW Hpro is in spain at the moment on holiday

HPRO travels everywhere dosen't he?'


He's Rich.

Yeah, I had one of those Kenwoods.

When it worked it was great. Instead of being fast, it had multiple laserbeams, so it would spin slower and read more at the same time, which = quiet. It also had a full 2 meg buffer, so it wasn't constantly "spinning up".

The bad news is they only lasted about 6 to 9 months :|

dang, that sounds like a nice cd-rom drive.

I'd imagine it's more of a microfracture in the CD itself that was weakened because of the stress. Any object which is spinning has any point on it accelerating towards the center. So there's a fair amount of stress at any given point, and a microscopic irregularity could lead to higher local stress concentration, which increases the fracture, which increases the stress, until a part flies off, and I'd imagine the imbalance would accelerate the process from there.

It's the same reason you often see failures in things like hip implants, even when the overall stress is less than the yield stress, local stresses near an irregularity can be greater than the yield stress, causing fracturing and ultimately device failure.

I still got it if you want it Krono, 5 bucks shipped, guaranteed DOA

[KronoLeginaire]

lol, nah.
