    摘要： An optical disk includes a first area on which user information is recorded, and a second area in which a plurality of marks radially extending are arranged in a track direction in the optical disk. Information about the reflectance of the optical disk is recorded in the second area. It is intended to optimize the amplification factor of the reproduced signal on the basis of the information about the reflectance of the optical disk in the second area. Control data and user data can be reproduced quickly and highly reliably without depending on the relationship between the reflectances of a recording area and a non-recorded area of the optical disk.

    摘要： An information-recording medium includes first and second recording layers each of which is formed of a phase-change material containing Bi, Ge, and Te, wherein the first recording layer is arranged nearer to a light-incident side of the laser beam than the second recording layer; a composition of Bi, Ge, and Te contained in the second recording layer is within a composition range surrounded by composition points B2, C2, D2, D6, C6, and B6 on a triangular composition diagram of Bi, Ge, and Te; and a difference (α−δ) between a composition α of Bi in the first recording layer and a composition δ of Bi in the second recording layer is −1.0 to 3.0 at. %. Thus, there is provided a two-layered information-recording medium with high recording-data reliability and excellent repeated-data recording durability.

    摘要： The object of the present invention is to provide a card connecting structure and a card connector used in the same which have a minimum width that allows the guidance of the card at the time of insertion and the fastening of the received card, and that makes it possible to satisfy specifications in which space for fastening is not provided on both sides of the card, and which can sufficiently protect the solder-connected parts of the contacts. The card connecting structure comprises a card 40 that has contact pads 41 on one end, and a card connector 1 that receives this end of the card 40. Fastening means 50 that fasten the card 40 to the circuit board are disposed on the other end of the card 40 from the contact pads. Metal guide members 30 that guide the card 40 are disposed on both sides of the housing 10 (in the lengthwise direction) of the card connector 1. Each of the guide members 30 comprises a flat-plate-form guide part 31 which guides the card 40, a fastening part 32 which is fastened to the housing 10, and a soldered part 33 which is disposed between the guide part 31 and the fastening part 32, and which is soldered to the circuit board.
