Backing storage refers to that which supplements the main memory. A direct access backing storage device is one that allows for data to be retrieved by going to the exact position of the data without following any order. This mode of access is made possible because each location on the storage medium has a unique address and thus the read/write head can go directly to the required location. Examples of direct access backing storage devices are magnetic disks (Hard disks and floppy disks).
