2. Description of Prior Art

A data storage apparatus, for example a hard disk, is an apparatus for storing digital data. The hard disk is a very common technical product. Now every computer includes at least one hard disk.

The self-monitoring analysis and reporting technology (SMART) is very important for the hard disk. The self-monitoring analysis and reporting technology is like the black box for the hard disk. There is a lot of information about the hard disk in the self-monitoring analysis and reporting technology (for example, the damage condition of the hard disk).

The damage hard disk will be connected into a computer and will be powered on to read the self-monitoring analysis and reporting technology in the hard disk by the engineer when the hard disk needs to be repaired. However, it is very dangerous that the damage hard disk is powered on again. The hard disk may be damaged more seriously.

Moreover, an external hard disk is a very common technical product as well. However, to register the external hard disk with a handheld device (for example, a smart phone) is very complicated.

FIG. 1 shows a block diagram of the first embodiment of the smart data storage apparatus of the present invention. A smart data storage apparatus 10 is applied to a handheld device 20 . The smart data storage apparatus 10 includes a dual interface memory unit 102 , a data storage unit 104 , and an antenna unit 106 .

The dual interface memory unit 102 includes a communication bus interface subunit 108 , a memory subunit 110 , a radio frequency interface subunit 112 , a current-to-voltage converting subunit 114 , and a voltage regulating subunit 116 .

The memory subunit 110 is electrically connected to the communication bus interface subunit 108 , the radio frequency interface subunit 112 , and the voltage regulating subunit 116 . The current-to-voltage converting subunit 114 is electrically connected to the radio frequency interface subunit 112 , and the voltage regulating subunit 116 . The antenna unit 106 is electrically connected to the radio frequency interface subunit 112 . The data storage unit 104 is electrically connected to the communication bus interface subunit 108 .

A wireless signal 22 is sent from the handheld device 20 to the antenna unit 106 . The wireless signal 22 is, for example, a radio frequency identification signal (RFID signal), or a near field communication signal (NFC signal). The wireless signal 22 is induced to generate an induced current 118 by the antenna unit 106 . The induced current 118 is sent from the antenna unit 106 to the radio frequency interface subunit 112 .

The induced current 118 is sent from the radio frequency interface subunit 112 to the current-to-voltage converting subunit 114 . The induced current 118 is converted into an induced voltage 120 by the current-to-voltage converting subunit 114 . The induced voltage 120 is sent from the current-to-voltage converting subunit 114 to the voltage regulating subunit 116 . The induced voltage 120 is regulated into a driving voltage 122 by the voltage regulating subunit 116 .

The driving voltage 122 is sent from the voltage regulating subunit 116 to the memory subunit 110 to drive the memory subunit 110 . A memory data 124 is fetched from the memory subunit 110 to the radio frequency interface subunit 112 .

The data wireless communication unit 126 is electrically connected to the data storage unit 104 .

The data wireless communication unit 126 is used to wirelessly transmit the information stored in the data storage unit 104 to the handheld device 20 . The data storage unit 104 is, for example, an external hard disk. The registration information of the data storage unit 104 is sent from the data storage unit 104 to the memory subunit 110 through the communication bus interface subunit 108 .
