    Oil industry is a prominent aspect of modern economy and as it were exploration activities are very important for continuity of oil production.
    The exploration activities involve the acquisition of data and processing.  As exploration activities increases in the modern world, the computer manufacturers are also working hard to produce super computer and their processing that are involved.
    Many firms are emerging fast and of course modern firms make use of computers, especially the mainframe computer which has a large memory space.  As the activities is in the increase, there is need to increase storage facilities because there comes a time when the main memory of computer will be unable to hold all information required.  This is where the secondary storage device called the magnetic tape comes to play.
    A general description of the system goals, facilities and applications are involved.
