Detailed explanation-1: -DVD-RAM is an optical media storage device. It differs from a traditional DVD in that data is stored in concentric tracks (like a HDD) which allows read and write operations to be carried out at the same time.
Detailed explanation-2: -Optical storage is any storage type in which data is written and read with a laser. Typically, data is written to optical media such as compact discs (CDs) and digital versatile discs (DVDs).
Detailed explanation-3: -Most of today’s optical disks are available in three formats: compact disks (CDs), digital versatile disks (DVDs)–also referred to as digital video disks–and Blu-ray disks, which provide the highest capacities and data transfer rates of the three.
