20080259133 | PIEZOELECTRIC ELEMENT, INK JET HEAD, AND INK JET RECORDING DEVICE - A piezoelectric element includes a pressure chamber member that has an opening | 10-23-2008 |
20080267039 | HOLOGRAPHIC RECORDING APPARATUS, HOLOGRAPHIC REPRODUCING APPARATUS AND HOLOGRAPHIC RECORDING AND REPRODUCING APPARATUS - 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. | 10-30-2008 |
20090103154 | RECORDING APPARATUS AND INFORMATION PROCESSING APPARATUS EQIUPPED WITH THE SAME - 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. | 04-23-2009 |
