taurus [48]2 years ago
4 0

Answer:

No the magnetic tape requires a tape drive mechanism

Explanation:

The data in magnetic tape consists of information that has been digitized into discrete numbers by means of of a recording device which can also be able to read the recorded data on the tapes

As the magnetized tape passes under a current carrying conductor, the data on the magnetized surface can be sensed

Due to the arrangement of the magnetic tapes in their stored format, the process of retrieving information makes use of serial access such that information retrieval is slow.
