Abstract
A portable card type data storage device with a large capacity and low power consumption is provided which enalbes two storage mediums with different features to be installed into a single slot of an information processing device. The card type data storage device 100 of the invention includes a case 10 having a connection slot 10a, a first connector 11 adapted to be inserted into and connected with a connection slot 201 of an information processing device such as a PC 200, a hard disk 13 housed in the case 10, a second connector 12 for connection with a semiconductor memory 18 inserted into the connection slot 10a, and a storage device control section 20. When the first connector 11 is inserted into and connected with the information processing device 200, the storage device control section 20 receives electric power from the information processing device 200, and makes the hard disk 13 and the semiconductor memory 18, which is inserted into the connection slot 10a and connected with the second connector 12, function as external storages of the information processing device 200. Thus, two storage mediums comprising the semiconductor memory 18 of low power consumption and the hard …
