Types of information storage media
Magnetic
Optical
Paper
Solid State Media
Magnetic storage media
Data is written using the polarity of magnets. Often used for backups or archiving data.
+ Low cost alternative for storage
+ High Mutability (data can be changed / deleted or rewritten easily)
- Can corrupt data if exposed to a strong magnet
e. g Magnetic Hard Drives and Tapes
Optial Storage Media
Written and read by a laser.
+ Low cost
+Portable
- Can be damaged easily
- Cannot be overwritten once data is written on the disk. (no mutability)
Examples:
CD’s
DVDS

Solid State Media
This is data that is stored using circuitry. This is the storage type often found in phones and many devices such as USB sticks.
+ Little heat produced as no moving parts
+ Durable as no moving parts (if you droppped your phone the data would be protected)
