Question

compare the data storage mechanism in magnetic and optical disks

Answer 1

The key difference between optical storagemedia, such as CDs and DVDs, and magnetic storage media, such as hard drives and old-fashioned floppy disks, is in how computers read and write information to them. One uses light; the other, electromagnetism

Answer 2

Optical disk drive- Uses laser tools to store and read information. A laser is used to read the information stored in the dots and then converted into a signal of electricity that gave an audio or visual output.
Magnetic disk drive- Uses magnetization process. A mechanical arm becomes the primary tool that uses the handle to read data from the device and write data to the disk.
