Detailed explanation-1: -Detailed Solution. The correct answer is option 2 i.e Magnetic tape.
Detailed explanation-2: -Unlike hard drives and solid state drives, optical storage media is separate to the drive unit, so let’s take a look at that first. The idea behind the use of light and a reflective media to storage digital data was first patented in 1970 by an American physicist, James Russell.
Detailed explanation-3: -Six categories of optical media are available to meet most storage requirements: CD-ROM, DVD-ROM, DVD-RAM, recordable media, write-once read-many (WORM) optical cartridges, and erasable optical cartridges.
Detailed explanation-4: -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.
Detailed explanation-5: -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.
