Compact discs (CD) are read from the inside out ... About an inch of the The inner radius of a compact discs is used for clamping and is used to identify the manufacturer ... These parts of the compact discs can not be copied with out side data and can not be damage with the exception of snapping the whole compact discs in half ... A compact disc that contents music has the inner band of data which is called the lead-in which holds the table of contents for the compact disc ... The table of content lets the compact disc know how to navigate around the disc ... Music on a compact disc start just outside the lead-in ... The larger the music track the grater the width is on the compact disc ... A compact disc can hold upwards to 80 minutes of music ... You can tell where the music is on a compact disc by the barker shades on the compact disc ... When the compact disc is not full you can tell be the lightness on the compact disc ... To tell where the tracks are on a music compact disc their are very thin faint circles that separate the tracks ... Unlike a vinyl record which is read by a needle which lies within the grooves a compact disc is read by a laser which allows it to be read with only the laser beam "touching" the data ... The laser beam enters the compact disc on the play side and travels through the compact discs clear plastic layer which picks up information from the data layer then bounces off the reflective coating on the back side of the data layer ... The reflected laser beam then travels back through the clear plastic layer out of the compact disc and into the compact disc player's detector ... The detector then helps the compact disc player convert the information carried by the laser into sound ...
