Explanation:
Detailed explanation-1: -All Optical media (CD, DVD, Blu-Ray etc.) have pits and lands. These are microscopic and represent the binary information of the data stored on the disc.
Detailed explanation-2: -CD/DVD-R discs do not have true pits and lands, but the unmelted, clear areas and melted, opaque places in the dye layer fulfill the same function as pits and lands on a pressed disc. To write data onto a disc, the optical drive uses this type of laser to make a series of microscopic marks in the dye.
Detailed explanation-3: -These bumps are where the digital data is stored in binary form. The areas where the Aluminum is closer to the bottom (plastic), are called Lands, and the opposite bumps are called Pits.
