IPC: G11B19/02
Filed: 1987-08-11
Abstract: PURPOSE:To detect a last position without an END mark by deciding that a block to record the data is a final recording block when the block continues in which the prescribed number of data is not continuously recorded. CONSTITUTION:A directory area 11b is the area to record the main data contents of the directory, for example, a file name, a date, a file size, etc. For an EOT address area 11, the track number of a final recording track EOT of a main data storing part at the time of recording the directory is recorded.

Title: Solar cell using metal substrate
Inventor: ANDOU MOTOAKI
IPC: H01L31/04
Filed: 1989-07-31
Abstract: PURPOSE:To enable a high voltage to be taken out by arranging such that at least the surface of an insulation film has a texture structure. CONSTITUTION:The title item consists of a metal substrate 1, an insulation film 2 with texture-structured surface, a metal electrode 3, an amorphous silicon photoelectric conversion layer 4, and a transparent electrode 5. Materials with improved conductivity such as chromium, titanium, aluminum, SUS, and silver are used for a metal electrode which is provided on the insulation film. It is desirable that the film thickness should be approximately 50-500Angstrom  and the surface is textured by recessed and projecting parts of the lower-layer insulation film. An amorphous silicon photoelectric conversion layer has a pin or nip junction and the inciding light is converted into electrical energy in this layer. Inciding light shows a higher value as incident light advances longer within the cell. Namely, the more the metal electrode at the lower part is textured, the more the incident light is reflected randomly on the electrode surface and scattered in various directions, thus achieving a high light current.
