Answer:
"In digital recording, a audio or video signal is converted into a stream of numbers representing the changes over time in air pressure for audio, or chroma and luminance values for video. This stream of numbers is saved to a storage device. To play back a digital recording, the numbers are retrieved and converted back into their original audio or video forms so that they can be heard or seen. The digitized number streams themselves are never actually heard or seen." Digital recordings (CDs, DVDs, or hard drives) are better because they are smaller and they don't get damaged as easily. Although Digital recordings have down sides to because if the number stream get changed the slightest bit it might not work any more.
"Analog recording is a technique used for the recording of analog signals which, among many possibilities, allows analog audio for later playback. Analog audio recording began with mechanical systems such as the phonautograph and phonograph. Later, electronic techniques such as wire and tape recording were developed."
