Storage allocation per application

摘要

A device is equipped with local storage arrangement such as HDD and a removable optical storage carrier input device. Removable carriers include storage applications that necessitate storage space for storing data items. A storage management unit allocates storage space of the local storage arrangement to the inserted removable optical storage carrier and the application stored therein. The management unit also attributes to the portion identification information respecting access rights granted to the application with respect to data items stored in the allocated portion. The application is given no access to data items stored outside the allocated portion.
