Abstract: An information processing apparatus determines, for each of packed objects recorded on one data-migration-source magnetic tape, whether or not to regenerate the packed objects by using objects included in the packed objects, generates a second packed object by using objects included in a first packed object determined as being regenerated, performs control of distributing and recording a plurality of second packed objects and parity data on a plurality of magnetic tapes, and performs control of recording a packed object determined as not being regenerated on a magnetic tape different from the data-migration-source magnetic tape.

Abstract: A liquid ejection device includes a liquid ejection head having a nozzle surface provided with an ejection port of a nozzle from which a liquid is ejected, a cap that comes into contact with the nozzle surface to cover the nozzle, an air pressure adjuster that adjusts an air pressure inside the cap when the cap is in contact with the nozzle surface, and a contact force adjuster that sets, equal to a first pressure, a contact force that is a pressure causing the cap to come into contact with the nozzle surface when the air pressure adjuster sets the air pressure inside the cap equal to a first air pressure, and sets the contact force equal to a second pressure lower than the first pressure when the air pressure adjuster sets the air pressure inside the cap equal to a second air pressure higher than the first air pressure.

Abstract: To allow printing through a more appropriate method when carrying out printing using a two-liquid type ink. A fixing agent amount setting method of setting a usage amount of a fixing agent, which is liquid for fixing an ink, which is a colored ink, on a medium, where a fixing agent density, which is an amount of the fixing agent to eject per unit area is made to correspond with a colored ink density, which is an amount of the ink to eject per unit area, and set to a value smaller than or equal to an upper limit value of a fixing agent density corresponding to a maximum fixing agent density at which color unevenness does not occur on the medium.

Abstract: An inkjet recording medium, comprising an ink-receiving layer containing a pigment, a binder and an inkjet ink-fixing agent comprising a cationic compound disposed on at least one surface of a base paper, wherein 50% or more by weight of calcium carbonate is contained in terms of a solid content based on a total amount of the pigment contained in the ink-receiving layer; 75 to 90 parts by weight of the pigment, 1 to 10 parts by weight of the binder and 5 to 20 parts by weight of the inkjet ink-fixing agent are contained based on 100 parts by weight of the ink-receiving layer; the drop water absorbency of the ink-receiving layer (according to the drop water absorbency defined in Japan Technical Association of the Pulp and Paper Industry, J. TAPPI, No. 32-2:2000 except that a drop water amount is 0.001 ml) is 200 seconds or less; and a Stockigt sizing degree according to JIS-P-8122 for the inkjet recording medium is 5 seconds or less.
