摘要： PURPOSE:To maintain satisfactory rotation driving by installing a magnetic sensitive material to the surface of a hub, in a state that a separation from the hub of the magnetic sensitive material has been prevented by a projection having a bulged part in the end part provided on the surface of the hub. CONSTITUTION:The titled medium consists of an information recording disk 10 and a magnetic sensitive hub 20, and constituted so that the sensitive magnetic sensitive hub 20 is installed to a through-hole part of the center of the information recording disk 10. A magnetic sensitive material 22 is formed by a ring shape having a through-hole for allowing a spindle to pass through the center, and on its surface, a through-hole to be engaged to a projection is formed so as to become a point symmetry to the through-hole. The magnetic sensitive body 22 is installed to the surface of the hub 20 in a state that it has been prevented to be separated from the hub 20, by bulged part 24 of the end part of the projection provided on the surface of the hub 20.

摘要： PURPOSE:To surely mount hubs on an information recording disk by inserting the respective cylindrical parts of two hubs, at least one of which is a magneto- sensitive hub, into the transmission hole of the information recording disk from both sides and bonding each other on the top parts of the respective cylindrical parts. CONSTITUTION:The information recording medium has a constitution where two magneto-sensitive hubs 21 having a spindle insertion hole 23 are installed in the transmission hole in the center of the information recording disk 10 from both sides. The hubs 21 consist of the cylindrical parts 21a and wing parts 21b and magneto-sensitive pieces 22 are installed in them. The cylindrical parts 21a of the hubs are inserted from both sides of the transmission hole of the information recording disk 10. As for the cylindrical parts 21a of the hubs inserted from both sides into the transmission hole of the information recording disk 10, on the respective top parts 24 they are bonded each other. In the transmission hole of the information recording disk 10, the respective top parts 24 of the cylindrical parts 21a of the hubs are bonded each other, for example, with a bonding material layer 25.

摘要： PURPOSE:To obtain a high carrier-noise output level ratio (C/N) even with low recording power by providing a recording layer which consists of a mixture composed of In and GeS and permits writing and/or reading of information by a laser on an amorphous polyolefin substrate. CONSTITUTION:The substrate 1 consists of the amorphous polyolefin such as atactic PP and propylene/ethylene copolymer. An under coating layer is provided on the surface of the substrate 1 and the recording layer 2 consisting of the mixture composed of In (Indium) and GeS (germanium sulfide) is provided thereon. In is preferably incorporated in the recording layer at the ratio within a 30-80wt.% range of the total weight of In and GeS. Metal oxide is incorporated in the form of discontinuous spots as the under coating layer into the recording layer 2 on the side in contact with the substrate 1, then the spot-like metal oxide 3 changes the boundary face characteristic between the substrate 1 and the recording layer 2. The higher C/N is thereby obtd. and the sensitivity is enhanced without increasing the output of the laser light.
