Save the environment
When you throw CDs and DVDs in the dustbin they are shipped to add more waste. This actually leads to bigger problems and harms the environment further. It contributes to the issue of global warming too. Also after throwing one has to produce them more for the future which leads to the materials of the planets being lost. Rather than throwing them you can do some other things with it which will help save the environment. You can store all the old ones and try to auction them. It could be that the ones which are useless to you might be of use to others. This is a time consuming process and also money will go in fees and postage. People who do not have experience of auctioning will find it all the more difficult. The easiest way is by selling the CDs/ DVDs online.

Digital format helping to store music
The process of encoding data on Cds/DVDs is complex but if explained well will be understood by all. A single spiral track containing data exists on a CD. The track begins in the center of the disc moving outside and has bumps. If you compare a CD to DVD the storage capacity of the latter is much more. There is a certain subcode data that is utilized to encode the laser position in the track and the song titles. Error-correcting codes are also present to avoid misreading of the bumps or errors. Interleaving of data is also done on disc of Cds/DVDs for it to recover easily from burst errors that are caused by scratches.
