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 traditional CD explode. That sort of velocity is technically achievable with 48x or 52x CD drives – precisely the form of efficiency metrics PC fanatics coveted within the early 2000s. Nevertheless, the MythBusters crew could not make a CD explode in a regular, 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 turn into vital weak factors because the RPM rises. When the forces exceed the disc’s structural integrity, it could actually tear aside explosively. Past ruining the disc, such an occasion also can harm the drive, doubtlessly sending shards of plastic flying at excessive speeds.
Many movies on-line present CDs exploding once they’re pushed to the restrict, together with high-speed footage from The Gradual Mo Guys capturing a disc coming aside at 170,000 frames per second, watch beneath.
In trendy drives (that are going extinct in the end), producers restrict the utmost velocity to cut back the chance of catastrophic disc failure. Enhancements in disc supplies and drive building additionally assist decrease the probability of such accidents. Nonetheless, the theoretical chance stays if the disc is considerably broken and the drive spins it quick sufficient.
