Optical storageBinary codeAnything stored on your computer is in essence stored through ones and zeros, this is the crux of binary code, it is ones and zeros which run the computer and does all tasks. What is optical storage?Optical storage is the method of reading data on a disk using a laser. To do this, the computer bounces a laser off the bumps and flats on the disk and depending on which one it hits the laser is reflected off in a different direction, these lasers are then interpreted as either ones or zeros by the computer, ones are bumps and zeros are flats, this binary code is what the computer can understand. As the disk spins the computer scans with lasers in a spiral which is only half a micrometer thick, that's 200 times smaller than an average human hair. This is a CD-ROM, notice it is ROM which means it is read only memory which cannot be altered. Types of Optical storage
