Abstract
A storage device has access protection functions, enabling the resolution of problems occurring when, despite the fact that the actual access restriction state has changed, this change is not correctly transmitted to the host device (information processing device). The access control method of a storage device performs driving at least for reading of storage media by means of a host device control system, in which said control system is notified of the replacement of said storage media when the access permission state of said storage media has changed, without the physical removal of said storage media from said storage device.
