| 20090111041 | ELECTROPHOTOGRAPHIC TONER - The purpose of the present invention is to provide an electrographic toner, which is used for an image forming method of electrophotography, and particularly, used for mono-component development. The toner has a stable charge property, can form a toner layer on a developing sleeve wherein the thickness thereof is suitable and uniform, can achieve long-life property while a high image density is maintained (an image having a high image density is printed even when a large number of printings are conducted in succession), and achieves small toner consumption. In order to achieve this, an electrophotographic toner is proposed wherein at least inorganic particles, conductive metal oxide fine particles and carbon black are adhered to the surface of matrix toner particles, and the inorganic particles are surface-treated with cyclic silazane and have the specific surface area of 100 to 175 m | 04-30-2009 |

| 20120118181 | DISC DRIVING APPARATUS - A disc driving apparatus includes: a recording and reproducing unit for recording or reproducing an information signal; and a print unit for performing printing to the printing surface of the disc-shaped recording medium. The print unit includes a print head contacting the printing surface when performing printing, a head feeding unit having a head support lever to which the print head is mounted, a guide cam having a cam guide portion extending in a movement direction of the head feeding unit, a moving cam having an forward path cam engagement portion engaged with the cam guide portion in the forward path and a return path cam engagement portion engaged with the cam guide portion in the return path; and a guide member guiding the movement of the head feeding unit between the initial location and the turnaround location. | 05-17-2012 |
| 20120120173 | DISC DRIVING APPARATUS - A disc driving apparatus includes a recording and reproducing unit for recording or reproducing an information signal for a disc-shaped recording medium having a printing surface and a print unit for performing printing to the printing surface of the disc-shaped recording medium. The print unit includes a print head which is pressed to the printing surface when printing is performed on the printing surface, a head feeding unit to which the print head is mounted, the head feeding unit moving along the printing surface of the disc-shaped recording medium, and a guide member for guiding the movement of the head feeding unit. When the print head is pressed to the printing surface while printing is performed on the printing surface, the disc-shaped recording medium is bent so that the printing surface becomes inclined. The guide member is disposed to be inclined according to the inclined state of the printing surface. | 05-17-2012 |

| 20110090770 | THERMAL-ASSISTED-MAGNETIC-RECORDING HEAD AND MAGNETIC RECORDING SYSTEM USING THE THERMAL-ASSISTED-MAGNETIC-RECORING HEAD - Provided is a thermal-assisted-magnetic-recording head capable of directing, to a magnetic recording medium, light in which the spot size is reduced to submicron order with high total optical propagation efficiency. A light coupling unit that guides light emitted from the light source into a magnetic head and a high-refractive-index core that couples with the light guided by the light coupling unit to lead the light to an air bearing surface are arranged in the magnetic head. The light coupling unit includes a plurality of thin-film-like cores that are separated from each other by a clad material. An upper part of the high-refractive-index core is placed between two thin-film-like cores. | 04-21-2011 |
