Advantages and disadvantages of optical disk

As we know, An optical disk is any computer disk that uses optical storage techniques and technology to read and write data. It is a computer storage disk that stores data by digitally and uses late beams to read and write data. Here this post gives information about the advantages and disadvantages of the optical disk to better understand this topic.

Advantages of optical disk compare to magnetic disk:
  • The storage capacity of the optical disk is more than a magnetic disk.
  • The optical disk is physical storage than magnetic disks and can not be damaged easily.
  • The magnetic disk is sensitive to be touched whereas optical disk is not.
  • Magnetic filed do not cause any effect an optical disk whereas they affect the magnetic disk.
  • The optical disk has a lot of data as special of the double side of the DVD.

  • The time required for positioning read-write head over the proper track.

Disadvantages of the optical disk:

  • The main disadvantages have cost both for the drive and the disks.
  • It is not quite as easy or as fast to copy an optical disk as it is to the software and hardware for writing disks.
  • More complicated drive mechanism.
  • Need careful handling.
  • Label optical disk for easy identification.
  • Use offline.
  • The risk to lose data.
  • Prone to scratches, dust, sticky prints.
