摘要:
A writable optical disc has an information writing track, and a guiding track for introducing a laser beam to the information writing track. The guiding track has prepit information recorded thereon, the prepit information including at least address information of the optical disc. The prepit information is recorded on the guiding track at a position where interference of adjacent guiding tracks with the prepit information is prevented. The information writing track is a groove track, and the guiding track is a land track.

A liquid crystal display apparatus is provided which requires a small, thin and compact area for mounting semiconductor chips for driving liquid crystal and, accordingly, has a reduced cost. Semiconductor chips for driving liquid crystal are mounted on a surface (for example, a first layer) of a multi-layer substrate. The surface has input lines to the chips and output lines from the chips. The input lines have lands for connecting adjacent multi-layer substrates to each other. At least one intermediate layer is formed between an upper layer and a lower layer, the intermediate layer having bus lines. The bus lines and the input lines of the first layer are connected to one another via through holes in the first layer. The output lines of the first layer and terminals of the third layer are connected to one another via through holes in the first, second and third layers.

A FPC tape carrier electronic component mounting structure comprises a plurality of cut out regions in a FPC tape carrier formed spatially along the length thereof, which regions define electronic component mounts. These cut out regions are contained within the confines of the FPC tape carrier and having a preformed substantially closed loop cut out boundary. Each of these cut out regions may contain at least one electronic component mount comprising a semiconductor integrated circuit chip electronic device electrically connected to at least one lead pattern formed on the carrier within the cut out region boundary. Slits or slit apertures are formed at one or more points along the cut out boundary. Securing, attachment is provided at one or more points along the mount boundary, which are provided at the regions of the slits or slit apertures to secure the electronic component mounts with minimal connection to the body of the tape carrier. Thereafter, the securing attachment may be easily severed in assembly line fashion with the mounts separated from the tape carrier and transferred via a transfer apparatus to a position of their assembly relative to electronic apparatus undergoing assembly. The securing attachment may be comprised of an adhesive flexible tape (FT) along the length of the tape carrier or may be one or more micro connectors formed from the carrier tape material and extending between the cut out regions forming the mounts and the body of the tape carrier.

An image data obtaining unit (102) obtains image data picked up by an image-pickup device. An identification information obtaining unit (101) obtains identification information of a device that is wirelessly communicated when the image data is obtained. An image data memory unit (104) stores, in association with each other, the obtained image data and the identification information obtained when the image data is obtained. The identification information obtaining unit (101) obtains the identification information of the device wirelessly communicated at a predetermined timing after the image data memory unit (104) stores the image data and the identification information in association with each other. A searching unit (106) searches image data associated with the obtained identification information among pieces of the image data stored in the image data memory unit (104). A display control unit (107) displays the searched image data on a display unit.
摘要:
An optical disk includes a substrate covered with an information recording layer. The information recording layer includes a recording material and a dispersion material dispersed in the recording material. The recording material absorbs recording light for recording information, and then generates heat. As the light refraction index of the recording material changes due to the heat generation, information is recorded on the recording material. The dispersion material has lower absorptance of the recording light and lower thermal conductivity than the recording material, and an external dimension smaller than a diffraction limit of reading light for reading information.
摘要:
On a recording medium, the version information indicating a version of the recording standard to which the information recording medium is adapted is recorded. Moreover, the normal recording condition information for recording information at a normal recording speed and the high speed recording condition information for recording the information at a higher recording speed than the normal recording speed are recorded. The recording condition information includes, for example, information about a write strategy for driving a laser light source. At the time of recording, the information recording device compares the version information on the information recording medium with the version information of the information recording device so as to judge whether or not the information can be recorded. When the judgment is made that the information cannot be recorded based on the version information, further the compatibility version information is compared with the version information of the information recording device so that a judgment is made as to whether or not the information can be recorded. In such a manner, the judgment can be properly made as to whether or not the recording can be executed on the information recording medium.
