Though it is unlikely to occur with most discs in most drives, there have been occasional reviews of discs exploding inside CD/DVD drives. Within the majority of these instances, the disc was already broken, and spinning it at excessive velocity was all it wanted to shatter.
When examined by the TV present MythBusters again in 2003, it took round 23,000 rotations per minute (RPM) to make a standard CD explode. That sort of velocity is technically achievable with 48x or 52x CD drives – precisely the type of efficiency metrics PC lovers coveted within the early 2000s. Nevertheless, the MythBusters workforce could not make a CD explode in an ordinary, unmodified drive and needed to resort to different strategies to push the disc to its breaking level.
If a CD spins too shortly, the centrifugal pressure appearing on it will increase dramatically. Even tiny scratches, hairline cracks, or manufacturing imperfections can change into crucial weak factors because the RPM rises. When the forces exceed the disc’s structural integrity, it could possibly tear aside explosively. Past ruining the disc, such an occasion may injury the drive, probably sending shards of plastic flying at excessive speeds.
Many movies on-line present CDs exploding after they’re pushed to the restrict, together with high-speed footage from The Sluggish Mo Guys capturing a disc coming aside at 170,000 frames per second, watch beneath.
In trendy drives (that are going extinct ultimately), producers restrict the utmost velocity to scale back the danger of catastrophic disc failure. Enhancements in disc supplies and drive building additionally assist reduce the chance of such accidents. However, the theoretical risk stays if the disc is considerably broken and the drive spins it quick sufficient.
