MAGNETIC TAPE

Magnetic tape is one of the most popular storage medium for data. The tape is a plastic ribbon with metal oxide material coated on one side which can be magnetised. In this, information can be written and also can be read by write/read heads.

Information recorded in the tape is in the form of tiny magnetised and non magnetised spots on the metal oxide coating. The magnetised spot represent '1' and unmagnetised spot represent '0' in binary code. The information can be accessed, processed, erased and can be again stored in the same area.

Advantages

1. It's storage capacity is large

2. It is easy to handle and is portable.

3. It's cost is less than other storage devices.

4. It can be erased and reused many times.

Disadvantage

1. It consumes lot of time.
