4 POINTS ON RECORD


1. Sound recording converts sound waves into electrical signals and stores them in a retrievable format.

2. There are two main types of recording: a) ANALOUGE - magnetic tape, vinyl record

                                                                   b) DIGITAL -  compact disc.

  3. On records, the signals are stored as a spiral groove; on tapes, they are recorded as varying levels of     magnetism on two tracks.

  4. On CD's, the signals are transformed into binary numbers, represented by pits and spaces.
