Seek time is the time taken by the read/write head to move from its current position to the track where data is to be accessed. This involves physically moving the head across platters, and therefore, it is the longest of the three components of access time in a movable-head DASD. Search time refers to the time taken by the controller to locate the specific sector on the track, and delay time is the time spent waiting for the data to rotate under the read/write head once it reaches the appropriate track. Transfer time is the time taken to read or write data once the data is located, which is comparatively much shorter than the other three components.
