A device-side write permission/denial designation setting means for setting a designation regarding write permission/denial to the medium; and a device-side write permission/deny designation setting means that logically combines the detected medium-side write permission/deny designation and the set device-side write permission/deny designation to determine the final setting for the access source device. 1. A secondary storage device comprising: logic means for generating and outputting a designation regarding write permission/denial. (2) medium-side write prohibition designation detection means for detecting a designation regarding write permission set based on the physical state of a predetermined location of the storage medium to be accessed, and a designation regarding write permission to the storage medium to be accessed; a device-side write permission/denial designation setting unit configured to logically combine the detected medium-side write permission/denial designation and the set device-side write permission/deny designation to generate a final write permission designation for the access source device; 1. A secondary storage device comprising: logic means for outputting; and display means for externally displaying a final designation regarding permission or disapproval of writing output from the logic means.
