How do you destroy digital media?
It depends on what you want to destroy. If it's a digitally recorded tape, just pull it out of the cassette and stretch it, cut it up or wad it up until it wrinkles.
If it's a CD or a DVD, I usually put mine in the microwave (1000 watts) and set the timer for three to five seconds. It really puts on a light show and smells bad, but you can watch the microwaves eat the metal layer right off the plastic. There definitely won't be anything left of the data.
The various devices that use digital media for storage (e.g. digital cameras, digital video cameras, digital voice recorders, computers, mp3 players) have gradually demanded faster and faster speed media for proper performance. The engineers that design the magnetic disks and flash memory used in digital media for storage have not only kept up with this demand but often exceeded it in anticipation of next generation devices.
Apple produces a number of products that are relevant to digital media. iTunes is a digital media player that is downloaded onto a computer and upload media too. iTunes allows the user to sort by genre, artist, and playlist. For media players that are more portable, try and iPod or iPad, which will also hold media, depending on the size of the product.
