How does magnetic storage work?
Information is saved using optical lasers on discs.
Magnetic storage works by encoding data as magnetic patterns on a medium, which are read and written using a read/write head.
Data is stored as electrical signals on a chip.
Data is encoded in binary format on paper.
What is one advantage of using magnetic storage?
Faster data retrieval than solid-state drives.
High storage capacity at a low cost.
Lower power consumption than optical storage.
High durability under extreme conditions.
What is a common disadvantage of magnetic media?
High storage capacity
Durability against environmental factors
Low cost of production
Susceptibility to physical damage and magnetic fields.
Name a common magnetic storage device.
USB Flash Drive
Solid State Drive (SSD)
Hard Disk Drive (HDD)
CD-ROM
How is data retrieved from magnetic media?
Data is retrieved using read/write heads that detect magnetic fields.
Data is retrieved using laser beams that read optical patterns.
Data is retrieved through chemical reactions that alter the media's surface.
Data is retrieved by heating the magnetic media to a specific temperature.
