Explain Storage process of magnetic disk and CD-ROM.
Answers
A magnetic disc is a storage device that writes, rewrites, and accesses data using a magnetization process. CD-ROM, is a type of computer memory that is stored on a compact disc and read by optical means.
What is Magnetic Disk?
Magnetic Disk has a magnetic covering on top that retains information in the form of tracks, spots, and sectors. Magnetic discs include hard discs, zip drives, and floppy discs, to name a few.
What is storage process of magnetic disk?
Both sides of the metal discs in magnetic disc drives are coated. To read or write data, these discs rotate at a high rate. The tracks are circular, and access arms put electromagnetic read or write heads between the slightly separated discs. These tracks store data in binary format. The storage capacity is quite great, allowing it to store any sort of data, including text, voice, and images.
What is CD-ROM?
Compact disc read-only memory, or CD-ROM drive reads digitised data recorded in the form of microscopic holes on an optical disc using a low-power laser beam.

Compact disc read-only memory, or CD-ROM drive reads digitised data recorded in the form of microscopic holes on an optical disc using a low-power laser beam.
A CD-ROM drive uses a low-power laser beam to read digitized (binary) data that has been encoded in the form of tiny pits on an optical disk. The drive then feeds the data to a computer for processing. The standard compact disc was introduced in 1982 for digital audio reproduction.
