It is far superior than previous storage mediums like tape cassettes and records. Record was the early storage mediums. It was



replaced by tapes. Tape cassettes enjoyed popularity for many years. Now, compact discs have completely replaced tape cassettes.

Quality of music stored on a cd is far more superior to that of a cassette. It has excellent audio output. It gives great purity of sound. Tunes and voice are very distinct. Makes listening of song and tunes more enjoyable. This is one of the main reason of its popularity among the listeners.

It offers better safety than that of tape cassettes. Tapes were prone to easy damage and breakage. Formation of fungus due to non use was also the minus point. A CD is much sturdier. It is usually damage proof and scratch proof in normal usage. Very rough use can only cause damage to a compact disc. It is also fungus proof. Hence, it can be stored for very long periods.



It has a great capacity for storage. A compact disc can typically store 700 mega bytes of music. That is a huge capacity considering

storage in mp3 file format. Mp3 format reduces the file size to nearly 15 per cent than its previous file formats. A song of 50 mega bytes can be reduced to 5 or 6 mega bytes in mp3 format keeping the sound quality intact. Capacity of a cd is one of its chief advantages.

A cd is very cost effective also. Mass production reduces the cost to a great extent. Secondly, competition among its manufacturers also helps in reducing the cost. Now, it has become highly affordable to the extent that it can be almost termed as cheap.
