Detailed explanation-1: -An optical disk drive uses a laser beam to read the data from the disk as it is spinning. It distinguishes between the pits and lands based on how the light reflects off the recording material. The drive uses the differences in reflectivity to determine the 0 and 1 bits that represent the data.
Detailed explanation-2: -Blu-ray. The Blu-ray disk has emerged as clear leader in today’s optical storage market. Unlike CDs and DVDs, which use a red laser to read and write data, a Blu-ray disk uses a blue laser, which dramatically increases capacities and data transfer rates over CDs and DVDs.
Detailed explanation-3: -An optical disk drive uses laser technology to write data to and read data from an optical disk. The optical disk drives use removable media.
Detailed explanation-4: -An optical disc drive (ODD) in a computer system allows you to use CDs, DVDs, and Blu-ray discs to listen to music or watch a movie. Most drives also allow you to write data to a disc, so you can create your own music CDs, video DVDs or even create of back-up copy of your important data files.
