Establishing the Maximum Speed of a CD-ROM Drive

Posted by michael on from the science-at-its-finest dept.

UnknownSoldier writes "Ever wondered how fast CD-ROM drives can spin their CDs before the CD will self destruct due to centrifugal force? This person was too, and has his results. (So much for those 100x drives)."

    Will the next computer snake oilish product be 'cd glue' to prevent you cds from falling apart, citing this paper? :)

    you could spin *both* the disc and the reading head (in opposite directions).

    My next GPLed project will involve CD-ROMs spining at 99x, and sharks with frickin' laser beams attached to their heads.

    something more exact then a laser reading pits and grooves burned into plastic that are invisible to the human eye? Pft...why would CONSUMERS have access to such technology.

  7. [ukquake] exploding CD-ROM drives by Yarn · · Score: 4, Funny
    From the annals of the UKQuake Mailing List

    There was a noise from the next office like toast popping, and Steve the senior consultant yelled in terror. "Has your toast popped?" I shouted? "Someone just tried to shoot me!" he replied. I walked into his office to see the occupants crowded around an open CD-ROM drive with the shattered remains of about half a CD in it. As we watched, the drive attempted to shut itself, made it about half way, and then opened again. It repeated this process about twice a minute, shutting a little more completely each time. Eventually it fully closed itself, though it is still opening and shutting regularly. We didn't find the other half of the CD (at least some of it is presumably still in the drive and is what was preventing it from closing) but we did find the front flap of the CD-ROM drive under Steve's desk, where it had fallen having been blown clear across the room, past his head, and colliding with his notice-board.

    Some points:
    • It was a Samsung 40-speed drive. You might want to avoid them.
    • It was a Hewlett-Packard CD-R that had come free with a USB portable CD burner. You might want to avoid them.
    • It was quite warm, though there was no direct sunlight hitting the drive. You might want to avoid that anyway.
    • Fear.

  8. no... what cd-roms really need by deathcow · · Score: 4, Funny

    What cd-roms really need is an eject button which doesnt write home to it's manufacturer (at book rates) for permission to eject a damned disc!

    How frustrating it is to push an eject button and watch a device deliberate for several seconds over SOMETHING before ejecting it's cargo!

    Basically, that button means "Your work here is done", so give me the disc, OK??
