Detailed explanation-1: -The name “Blu-ray” refers to the blue laser (actually a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.
Detailed explanation-2: -Blu-ray technology gets its name from the blue-violet laser that is used to read Blu-ray disks. Compared to a DVD’s red laser, a blue laser permits more information to be stored at a greater density.
Detailed explanation-3: -Unlike DVD technology, which uses red lasers to etch data onto the disc, the Blu-ray disc technology uses a blue-violet laser to record information. The blue-violet laser has a shorter wavelength than the red lasers do, and with its Smaller area of focus, it can etch more data into the.
Detailed explanation-4: -Blu-ray is an optical disc format like CD and DVD. Blu-ray discs can hold more information than other optical media, because of the blue lasers that the disc drives use. A single Blu-ray disc can hold up to 25GB of data.
Detailed explanation-5: -Compact discs, DVDs, and Blu-ray discs are common types of optical media that can be read and recorded by such drives. 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.
