Optical disk, recording/reproducing method thereof, and optical disk apparatus with employment of optical disk

A recording apparatus includes a first light source irradiating first laser light, a second light source irradiating second laser light, an optical spatial modulating unit applying information to the first laser light, and an objective lens collecting the first laser light and the second laser light at different positions on the same optical axis. A hologram recording operation uses a first optical path and a second optical path. The information light is conducted to the objective lens along the first optical path. The reference light is conducted to the objective lens along the second optical path. At the same time, an address/servo control operation is carried out by employing a third optical path along which the second laser light is conducted to the objective lens. The DVD recording operation uses the second optical path. The CD recording operation uses the third optical path.

Recording apparatus and information processing apparatus equipped with the same

A holographic recording apparatus causes reference light and information light to interfere with each other, and records the interference pattern in a recording medium. The holographic recording apparatus has an objective lens and a focus position controller. The objective lens focuses both the reference light and the information light at a focus position of the recording medium. The focus position controller changes the focus position into a predetermined position on the light path of the reference light.

Holographic recording apparatus, holographic reproducing apparatus and holographic recording and reproducing apparatus

A piezoelectric element includes a pressure chamber member that has an opening communicating with a nozzle, a vibrating plate that is disposed on the pressure chamber member so as to cover the opening, a lower electrode that is disposed on the vibrating plate, a piezoelectric body that is disposed on the lower electrode, an upper electrode that is disposed on the piezoelectric body and in a region opposed to the opening, and a lead electrode that is disposed on the piezoelectric body, that extends from the upper electrode, and that has a width smaller than that of the upper electrode. The piezoelectric body includes a groove portion that is disposed in a predetermined region along an edge portion of the opening and an inactive region (piezoelectric inactive region) that is a region other than the groove portion, that is disposed along the edge portion of the opening, and that does not substantially serve as a piezoelectric element. The lead electrode is disposed in the piezoelectric inactive region.

Piezoelectric element, ink jet head, and ink jet recording device

An inkjet recording apparatus includes an absorber configured to abut a nozzle surface of a line head to absorb ink adhered on the nozzle surface. A portion of the absorber which corresponds to an opening of a nozzle is removed. The absorber is configured to abut the nozzle surface except for a portion near the nozzle. Ink remaining on the nozzle surface is absorbed by the absorber. Thus, when the nozzle surface is wiped with a blade, accumulation of a large amount of remaining ink is prevented.

Inkjet recording apparatus

A printer includes: a recording section for recording information on a recording medium; a medium carrying mechanism provided in an apparatus casing having an eject port that is opened in an upward direction or in a slanted upward direction; a medium accommodating section extending in a vertical or slanted vertical direction that defines a medium accommodating space that is continuous with the eject port; and an upward medium carrying mechanism that carries the recording medium upward by an amount according to the size of the recording medium stored in a size memory device, so that the re cording medium projects from the eject port by a predetermined constant length.

Recording apparatus

An inkjet recording apparatus includes a moving device which moves an inkjet head relative to a recording medium. When the head is moved relative to the recording medium by the moving device, a nozzle of the head ejects ink onto the recording medium, so that recording is carried out. The inkjet head includes (a) pressure chambers containing ink, (b) nozzles communicating through the pressure chambers, (c) piezoelectric elements, (d) piezoelectric actuators that deform to increase or decrease the capacities of the pressure chambers due to piezoelectric effect of the piezoelectric elements, and (e) a controller for driving the actuators at a frequency not less than 20 kHz. This structure allows the actuators to operate substantially noiseless, and an image can be recorded at higher speed.

Formed on a first face of a head main body are nozzles. Formed on an opposite second face of the head main body are actuators. A driver IC is, at its both ends, fixedly supported on the second face of the head main body so that the driver IC lies astride the actuators, in other words, the driver IC is mounted on a side of the head main body opposite to the ink emitting side. One ends of relay terminals formed on the second side of the head main body are coupled via respective wires to a printer main body. The other ends of the relay terminals are coupled via bonding wires to corresponding input terminals of the driver IC. Output terminals of the driver IC and input terminals of the actuators are connected together by bonding wires.
