Hi everyones..thanks to read.
I've noticed with two different internal atapi cd-rom drives that
there's seems to be some kind of loose bearings of some sort on
the spindle assembly. I've noticed that with my old failed cd-rom
drive from 1999. The brand new one (LG 52x) seems also to have
those bearings or whatever, moving loosely inside the spindle assembly.
Any infos about that? TIA

Most of the spindles I've seen had sleeve-bearings, in that case the
looseness would simply be wear. Is it possible you're just hearing
something else rattling or vibrating? Since your old drive has
failed you could open it up and see what's making the noise, but if
you try to run it don't look into the laser, wear appropriate goggles
if you have them.

Completely Normal. When the CD Spins Up, those will reposition normally due
to the centrifugal force.
 
My son and I dismantled a new Liteon DVD drive that someone had "had a go
at" as it had what would have been the condition you describe. A kind of
rattling noise when the drive is moved. Sounded like the bearing had
disintegrated. When the disc platform on the spindle was removed, beneath
was half a dozen or so ball bearing balls which seemed to be just sitting
between the motor and this disc the CD sits on. No obvious channel for them
to form a bearing as such. I assumed they may have been a balancing
mechanism, thrown out by centrifugal force. Doesn't seem to affect the
operation of the drive.

Thanks to everyones for the replies. It's sad that i didn't kept the old
drive because i would have check how this is assembled. I've done a 30
minutes search on google with different keywords and could not find any
details about the spindle assembly in those drives. The only thing i've
found is that it's part of the balancing mechanism like some of you did
said.See this link:
