Optical storage mediums such as computer optical discs, also known as compact discs (CD), can physically show digital data as binary code by microscopic ditches on the reading surface of the disc. As binary data is either 1 or 0, having a ditch can represent 1, and not having could represent 0, hence as the laser reads the disk, it will get a reflection of the data by reading whether there is a ditch in channel or not.taxman said:How do optical storage mediums physically show digital data as binary code?
