Basic Differences Between Optical and Magnetic Storage Devices:


#
Optical Storage Devices
Magnetic Storage Devices
1
Stores data as patterned image
Stores data in magnetic form
2
Optical storage devices offer lesser capacity
Magnetic storage devices offer much higher capacity
3
Requires LASER light to read and write data onto the disc
Doesn’t require LASER heads to read and write data
4
Slower data read and write
Faster data read and write
5
Data on the disk will not be damaged by magnetic fields
Magnetic field can destroy the data stored on Magnetic storage devices
6
Optical storages can be readable, writable and re-writable
Magnetic storage devices are always readable and re-writable
7
Optical storage devices require additional drives to function
Almost all magnetic storage devices comes with built-in drives
8
Easy and safe to take around
Not as safe as optical storage devices to take around
