Patent ID: 7447853

Claim:
A data copy device for directly copying data from a source medium ( 140 ) to a target medium ( 150 ) connected in common to an IDE interface, comprising: an IDE module ( 130 ) for providing the IDE interface such that a data bus (D [ 15 : 0 ]) and an address bus (AD [ 2 : 0 ], CS [ 1 : 0 ]) are connected in common to the source medium and the target medium, and a data input/output signal combination (DIOR, DIOW) is connected to a data read/write signal combination (rd_ 1 , wr_ 1 ) for the target medium; a switch module ( 310 ) for selectively providing an IDE read control signal (DIOR) or an IDE write control signal (DIOW) of the IDE interface as a data read signal (rd_ 0 ) for the source medium in response to an external selection input (sel); and a control module ( 110 ) which controls the switch module through the external selection input (sel) so that the signal combination (DIOR, DIOW) can be provided as a data read/write signal combination (rd_ 0 , wr_ 0 ) for the source medium, sets operational parameters for the source medium and the target medium through the IDE interface such that a Command register of the source medium and a Command register of the target medium are set to READ-mode and WRITE-mode, respectively, confirms whether the source medium and the target medium are in READY states, sets the address bus to DATA-mode, controls the switch module so that the IDE write control signal (DIOW) can be provided as a data read signal (rd_ 0 ) for the source medium, and provides the IDE write control signal (DIOW) to initiate data copy from the source medium ( 140 ) to the target medium ( 150 ).
