In a storage medium which has a number of areas, access to any area is controlled in accordance with whether or not access to another area is possible, and thereby, destruction of data due to malfunctioning or a wrong operation is prevented. A link control part which controls access to the second area based on the information on access to the first area is provided, and access to the second area is controlled on the basis of whether or not access to the first area is possible. Control becomes possible, such that access to the second area becomes impossible in the state where access to the first area is impossible, while access to the second area becomes possible in the case where access to the first area is possible.
