Title: Optical recording medium, production thereof and recorder/reproducer
Inventor: FUJI HIROSHI
IPC: G11B11/10
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To obtain a super resolution magnetooptic recording medium in which the recording conditions and reproducing conditions can be controlled. SOLUTION: A magnetooptic recording disc 1 has an information recording region IA and a recording condition control region OA. The information recording region IA has an information recording/reproducing region 13a where magnetic super resolution takes place. The recording condition control region OA has a reproduction layer 13b for controlling the recording conditions where magnetic super resolution does not take place. A recording layer 14 is formed contiguously to these layers 13a, 13b. The recording condition control region OA can control the recording conditions because magnetic super resolution does not take place and can determine the optimal recording conditions of the magnetooptic recording disc 1.  When information is recorded in the information recording region IA using the optimal recording conditions, recording conditions of the information recording region IA can be controlled and the optimal reproducing conditions can be determined.

Title: Vector data processor
Inventor: KINOSHITA SEIICHIROU
IPC: G06F15/78
Filed: 1983-07-06
Abstract: PURPOSE:To ensure the use of a vector register with high efficiency under a simple control by providing individually plural vector registers which can perform both writing and reading at a time via a vector data processor and write/ read address registers. CONSTITUTION:An OP code designates the multiplication to perform the instructions which designate vector registers VR0, VR1 and VR2 through an arithmetic result store operand part, the 1st operand part and the 2nd operand part respectively. Then the OP code designates the addition to deliver the instructions which designate VR3, VR0 and VR4 through the arithmetic result store operand part, the 1st operand part, the 2nd operand part respectively. Thus the accesses of the VR0 overlap each other. However the former instruction is equal to a writing action carried out by the control of a writing address register 11, and the latter instruction is equal to a reading action done by the control of a reading address register 21. Thus a simultaneous access is possible with both instructions. As a result, the latter instructions are started before the execution is through with the former instructions.

Title: Magnetic card and authenticy decision method therefor
Inventor: KATO MASAHIRO
IPC: B42D15/10
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To display a printed image on a magnetic card and to make it difficult to identify the card in its external appearance by setting a security track in an addition area of halftone dots of the magnetic ink. SOLUTION: An image is printed by the screen printing and formed as an aggregate of halftone dots 1. An area where a security track is set and a magnetic pattern is read for decision of autheniticity of a magnetic card is defined as an area A, for example, where the dots 1 of the magnetic ink are added. The area A has the intermediate density showing a certain degree of gradation change in its reading direction. Then a magnetic pattern 2 is formed based on the addition state of dots 1 of the magnetic ink set by the ordinary screen printing. Therefore, the output varies at every added position of the dot 1 and this output variation reduces and increases at the small and large parts of dots 1 respectively. Furthermore, these output variations occur in degrees according to the sizes and the number of dots 1 at a part where plural dots 1 are arranged in a row.
