Optically Readable Media
Floppy disk, hard disk, and magnetic tapes are examples of magnetic storage media, while DVD is an example of optically readable media.
DVD
A DVD (Digital Versatile Disc) is an optical storage device that uses laser technology to read and write data. It is commonly used for storing videos, music, software, and other types of data. The data on a DVD is written in pits and lands on the surface of the disc, which can be read by a laser beam in a DVD drive.
Advantages of DVD
- High storage capacity: DVDs typically have a larger storage capacity compared to floppy disks and CDs, making them suitable for storing large files.
- Durability: DVDs are more durable than floppy disks and magnetic tapes since they are less prone to damage from dust, scratches, and magnetic fields.
- Portability: DVDs are compact and lightweight, making them easy to transport and store.
Conclusion
In summary, a DVD is an optically readable media that offers high storage capacity, durability, and portability. It is a widely used storage device for various types of data and is superior to magnetic storage media in terms of reliability and performance.
