    摘要： The present invention provides a flame-retardant resin composition comprising 100 parts by weight of a bromine-containing copolymer composition containing 1 to 40% by weight of bromine, and comprising 0 to 30 parts by weight of a flame-retarding adjuvant and 0.5 to 30 parts by weight of a polyorganosiloxane-reinforced resin component obtained by polymerizing a vinyl monomer (d) in the presence of a polyorganosiloxane polymer. The flame-retardant resin composition of the present invention has attained a remarkably higher flame retardancy by the inclusion of a polyorganosiloxane-reinforced resin. A significant improvement in the dripping phenomenon has also been achieved. Further, this composition exhibits superior impact resistance and moldability, and a superior outer appearance in the formed products.

    摘要： A pole layer has a track width defining portion and a wide portion. The pole layer has: first and second side surfaces located opposite to each other in a first region extending from a medium facing surface to a position at a distance of 10 to 300 nm from the medium facing surface; third and fourth side surfaces located in a second region other than the first region; a fifth side surface located at the boundary between the first and second regions and connecting the first and third side surfaces to each other; and a sixth side surface located at the boundary between the first and second regions and connecting the second and fourth side surfaces to each other. The distance between the first and second side surfaces taken in the track width direction decreases with decreasing distance from the top surface of the substrate. The angle formed by the third and fourth side surfaces with respect to the direction orthogonal to the top surface of the substrate is smaller than that formed by the first and second side surfaces with respect to the direction orthogonal to the top surface of the substrate.
