ABSTRACT:
A storage device executes a program matching a removable storage medium. The device has a drive unit for reading the storage medium, a program memory for storing a program module required for processing of a storage device and a module list, a random access memory, and a processor for performing access processing of the data of the storage medium by referring to the module list and executing the program module. The processor reads the program module stored in the storage medium, develops the program module in the random access memory, and registers the read module in the module list. The programs which run on an external storage device are distributed and recorded on the ROM of the external storage device and on the removable medium which is inserted into the external storage device, and are read and executed whenever necessary, so the ROM capacity required by the external storage device can be decreased, and the programs which run on the replaceable external storage device are recorded on the replaceable storage medium and are read and executed whenever necessary, so the programs matching with (optimized for) the features of the respective replaceable medium can be executed.
