Explanation

The statements Capacity to store large amount of data. and Data quality gradually erodes. state the advantages of magnetic tape.

  • Magnetic tape is a medium for magnetic recording, made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed based on magnetic wire recording.
  • Devices that record and play back audio and video using magnetic tape are tape recorders and video tape recorders respectively. A device that stores computer data on magnetic tape is known as a tape drive. Magnetic tape revolutionized sound recording and reproduction and broadcasting. It allowed radio, which had always been broadcast live, to be recorded for later or repeated airing.
  • It allowed gramophone records to be recorded in multiple parts, which were then mixed and edited with tolerable loss in quality. It was a key technology in early computer development, allowing unparalleled amounts of data to be mechanically created, stored for long periods, and rapidly accessed.

Advantages

  • A major advantage is that it has the capacity to store large amounts of data very easily.
  • A single magnetic tape cartridge can store large amounts of data up to 1 Terabyte. Large cartridges are used by big companies and institutions that require continuous recording and backup of data.
  • Data collection can go on without interruption overnight or for an entire weekend.
  • Magnetic tape can be recorded over and reused repeatedly.
  • Large amounts of information are stored.
  • Magnetic tape is inexpensive and budget friendly.
