When Spun Really Fast, CDs Explode

Posted by chrisd on from the vinyl-wouldn't-hold-up-very-well-either dept.

Anonymous Coward writes: "Ever wonder why cd-rom/cd-rw drives are not getting any faster? Wonder why they heat up? This page has a rather amusing experiment where they put various CD's into something that can spin up to 30,000RPM and found that most cd's explode at just around 28,000RPM. Oh and they seem to like using Corel CD-ROM discs for their experiment." Update: Yep, it's a dupe...

    They should at least have chosen AOL CDs to destroy. Sheesh.

    A lot of bands might consider exploding CDs a feature. :-)

    I can see it now, the RIAA manufacturing discs that experience structural failure when you spin them faster than 1X to rip them....

    oh boy.

    Wonder what happens if you spin a floppy at 30,000 rpm? :-)

  5. More Explosions! by Inexile2002 · · Score: 5, Funny

    I want to see more of this kind of story!

    I want to see what else can explode in my box. I want to see what happens (with big color pictures) to to a hard drive at 20000 atmospheres of pressure. I want to see ASUS vs ABit mobo's head to head for resisting g-forces. I want to see what happens when you force 100,000 volts through a cat-5 cable.

    Isn't this what the internet is all about, pictures of stuff exploding, videos of people endangering their lives for my tittlation while discovering what happens if you fill a case with gasoline and run it as a server. Get cracking people.

      What happens when guys in IT departments get bored or "fed up" with hardware? Try hooking up common computer cables and connectors to 110vac for the purpose of destruction =) I especially like VGA killer and the "powered" hub!

    Actually, it's a little-known fact that all CD-ROMs do keep the CD stationary, and simply spin the rest of the universe around it. True fact. ;)

    Yeah, right. Next you're gonna tell me that CDs are flat and if you read too far you'll fall off the edge.

  10. A faster way (2,466X) by carambola5 · · Score: 5, Funny
    I take no credit for this, but I remembered reading an interesting comment on the last time slashdot posted something like this. All credit should go to labradore:
    This is a good way to get a fast CDROM drive:
    1. Buy a 10,000x10,000 dpi scanner with firewire interfeace
    2. Write cdrom image analysis algorithm.
    3. Scan cdrom image into temp hard drive space and analyse, extracting data
    This is based on these rough figures:
    • A cdrom is approximately ( PI*5^2 - PI*0.75^2 )= 76.75 sq. inches of data surface
    • If a cdrom has about 5.6 billion bits on that surface then the density is roughly 76 million bits per square inch.
    • That works out to about 8,800 bits per linear inch. Assume you will need a little better resolution than that because there is some empty space between the dots on a cd surface. 10,000dpi aught(sic) to be good enough.
    Assuming that the scanner is faster than the firewire (400Mbps) and 10% overhead for the data transfer, each cd image will be approx. 7.3 billion bits, taking just over 20 seconds to transfer. This device is a 2,466x speed CDROM "drive". Put that in your Pentium and smoke it! Scanner and algorithm design left as an excercise for the reader.

  11. If Intel made CD-ROM drives... by guttentag · · Score: 4, Funny
    If Intel made CD-ROM drives, we would start seeing the following in 95% of new PCs:
    1. A giant fan aimed at a heat sink attached to the spindle that grips the CD
    2. Pressurized CD-ROM drives
    3. A sticker on the "5x-the-speed-of-sound" drive stating that by using this CD-ROM drive, you agree that the speed of sound is one-tenth the speed the rest of the world claims.
    One of the above would be appended to what we know today as a 24x CD-ROM drive.
