Magnetic Tape:



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

    Information record in the tape is in the form of tiny magnetized and non magnetized spots on the metal oxide coating. The magnetized spots represent ‘1’ and un magnetized spots 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 less than other storage devices.

4.    It can be erased and reused many times

Disadvantage :

1.    It consumes lot of time
