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)."

    Score 3? For what? Being wrong, at length? - smirkleton

  2. speed of sound?? by kinko · · Score: 1, Redundant
    A point on the periphery of the disc will be moving with 213 metres per second, slightly more than half the speed of sound. Can the disc take that?

    Uh, isn't the speed of sound about 300-330 metres per second? Depends what he means by slightly...

    .. and then spin the lasers in the opposite direction to the CD spin

    As long as you're throwing latency considerations to the wind, why not just build a plain old CD-ROM drive that reads the entire disc on load into an onboard 700M memory buffer, and subsequently serves data just as fast as you can transfer it?
