A recording apparatus, method, recording medium, and program for recording data files, according to a FAT system, on an information-recording medium, regardless of the capacity of the information-recording medium. A FAT block of a size corresponding to the capacity of a FAT-block SDRAM is sequentially copied from the top of a FAT recorded in the information-recording medium to the FAT-block SDRAM. A block number is recorded in control data created in response to the FAT block in the FAT-block SDRAM. The number of free clusters is counted. If free clusters are available, the number and total capacity of the free clusters are recorded, the cluster address of the first free cluster is recorded, and a loadable/unloadable flag set to loadable is recorded. The present invention is applicable to video cameras.

Recording device, recording method, recording medium, and program

A circuit substrate includes a first rigid substrate having a plurality of land portions located at a predetermined interval on one surface, a second rigid substrate having a plurality of second land portions located at a predetermined interval on one surface and a flexible wiring board sandwiched by the first and second rigid substrates and which has a plurality of third land portions corresponding to the first land portions on one surface and a plurality of fourth land portions corresponding to the second land portions on the other surface. In this circuit substrate, the second and fourth land portions are displaced from each other relative to the first and third land portions and at least part of the first and third land portions and at least part of the second and fourth land portions are electrically connected to each other, respectively.
