direction of movement of the magnetic arm is changed. In this scheduling method, the movement of the magnetic arm is similar to the dispatch of an elevator, so it is also called the elevator scheduling algorithm.4. Cyclic scanning algorithm (cscan): The cyclic scanning scheduling algorithm is improved on the basis of scanning algorithm. The magnetic arm changes to a single movement, by the outward. The current position begins to select the visitor of which cylinder is closest to the current on
