- Magnetic Tape
- Magnetic Disk
- Optical Disc
- Flash Memory
#1 – Magnetic Tape
Magnetic Tape It is one of the oldest technology to store data. Magnetic tape was invented to record sound in 1928 by Fritz Pfleumer, a German scientist.
A thin plastic ribbon is used to store data in magnetic tape which is coated by magnetic oxide. Magnetic tape is also widely used in modern times. If we talk about the storage capacity of modern magnetic tapes, then it is capable of storing up to 10 TB of data.
#2 – Magnetic Disk
magnetic disc Computer also has a secondary memory which uses magnetization process to read, write data. The magnetic disk is covered with a magnetic coating, it stores the data in the form of tracks, sectors and spots. The most modern type of magnetic disk is the hard disk, in which up to 20 TB of data can be stored.
#3 – Optical Disc
Optical Disk It is a round shiny disc in which a laser beam is used to store the data. Up to 50 GB of data can be stored in the Blue-ray Disc, the most modern type of optical disc.
Examples of optical discs under secondary memory CD, DVD And Blue Ray Disc Is.
#4 – Flash Memory
All USB devices used to store data come under flash memory. flash memory They are small in size but have a high capacity to store data. Data can be stored for a long time in flash memory. This memory does not spoil too quickly. Flash memory is widely used to store data at present.
