This disc will self-destruct in 5 seconds
The ticket came in just as I returned from break.
“Just inserted a disc into machine – made awful noise and ejected the disc with it in 2 pieces!”
They weren’t kidding. This is what the disc looks like now:
The more seasoned among you will probably already have spotted how this happened. Take a closer look at the centre of the disc:
See the fractures around the inside of the centre hole? Well, just like cracks in a car windscreen, they only get bigger with use. When you put a CD like this into a 52x drive, the stress from being spun at around 10,000RPM causes those cracks to creep larger, until… well, they get very large indeed, and your disc doesn’t really work any more.
And also scares a new teacher who only started yesterday.
