Abstract: An ink refill container includes a container main body including an ink storage chamber, an ink outlet-forming portion provided on an end portion of the container main body forming an ink outlet that allows the ink to flow out from the ink storage chamber, and a valve provided in the ink outlet-forming portion configured to openably seal the ink outlet, in which the ink outlet-forming portion includes a positioning portion on an outer side of the ink outlet-forming portion. in which the positioning portion is closer to the container main body than the valve is to the container main body in a central axis direction of the ink outlet, and in which the positioning portion partially abuts against an ink tank when the valve is opened for refilling the ink to the ink tank, to thereby position the valve relative to the ink tank.

Abstract: A data writing control device enable quickly writing data to optical discs. A reading process unit 62a, 62b reads data in predetermined read units from a storage device (hard disk drive 14) that has a head and stores the data. A storage unit (buffers 63a and 63b) has a storage area for storing the read units of data read by the reading process unit 62a, 62b. A writing process unit 64a, 64b acquires data stored in the storage unit in write units, which are smaller than the read units, and supplies the acquired write units of data to an optical disc drive is connected as a peripheral device.
