Abstract
The present invention enables connection and a high-speed access to a plurality of electronic apparatuses having different types of built-in interfaces.
The present invention provides an external storage apparatus including: storage means 22; an interface controller A21 and an interface controller B24, each having a different type of built-in interface control block for carrying out a data writing and/or reading into/from the storage means 22; and connection means 26 for selecting and connecting one of the interface controller A21 and the interface controller B24 to the electronic apparatus. It is preferable that the connection means 26 be constructed so as to select one of the interface controller A21 and the interface controller B24 according to a control from the electronic apparatus.
