Explanation:
Detailed explanation-1: -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-2: -An optical disk drive (ODD) uses a laser light to read data from or write data to an optical disc. These include CDs, DVDs, and Blu-ray discs.
