PURPOSE: A device and a method for supporting transaction on a logical disk is provided to improve system for supporting a data transaction. CONSTITUTION: The device for executing a data transaction is provided with at least one storage device adapted for receiving data as continuous data blocks and storing the data in respective physical locations and a control circuit. The control circuit is constituted so that the continuous data blocks can be transmitted to at least one storage device and at least several data blocks and a parameter indicating the identification of the data transaction, the identification of a recorder in the transaction state and the locations of the continuous data blocks can be written in at least one storage device. The control circuit is constituted so that the state of the data can be converted for completing(committing or canceling) the data transaction by using several instruction parameters. When a failure of the device is generated prior to the completion of the transaction, that is, the commit or cancel of the transaction, the complete recovery of the device can be easily performed by using the data stored in the data blocks.
