A recordable player has an external storage device to advantageously extend the capacity, facilitate the portability and provide the aseismatic design. The external storage device is additionally connected to a DVD or VCD recordable player. A USB transmission port or an IEEE 1394 transmission port is embedded in the DVD or VCD recordable player. Thus, data transmission between the player and the external storage device may be made through a USB transmission line or an IEEE 1394 transmission line. Therefore, AV data can be transferred to the external storage device from the DVD or VCD recordable player such that the AV data can be edited, rewritten and deleted. In addition, the data in the external storage device also can be transferred back to the DVD recordable player so that the data can be recorded and played.
