Which of the following is not a magnetic disk?

Correct option is B

DVD (Digital Versatile Disc) is not a magnetic disk but an optical disk that uses laser technology to read and write data. Magnetic disks, such as disk packs, Winchester disks, and Zip disks, rely on magnetic storage to record data, which differentiates them from optical disks.

Important Key Points:

1. Magnetic disks store data using magnetic patterns and are rewritable.
2. Optical disks, like DVDs, use laser beams for data reading and writing.
3. DVDs are more commonly used for media storage, while magnetic disks are used for data-intensive applications.

Knowledge Booster:

• Disk pack: A magnetic disk storage system used in early computers.
• Winchester disk: A magnetic hard disk drive with high storage capacity.
• Zip disk: A portable magnetic disk used for data storage and backup.
