    Abstract: Disclosed is an adjustment apparatus for adjusting an optical pickup capable of recording and/or reproducing plural optical discs of different sorts. The adjustment apparatus is an optical disc for adjustment (1) having a first signal recording layer (5) having a physical format in common with a CD and a second signal recording layer (7) having a physical format in common with a DVD. On the first and second signal recording layers, there are concentrically recorded EFM modulated data. The respective signal recording layers are provided with recording areas (8), (9) not overlapped with each other.

    Abstract: An optical pickup device includes a feed screw to move an optical pickup having an objective lens radially on an optical disc, a sliding member provided for slidable movement in relation to the optical pickup, and connected to the optical pickup by a coil spring that forces a shutter in a direction of unmasking the objective lens, and a connection member that connects the feed screw and sliding member to each other. As the feed screw is rotated, the sliding member moves the optical pickup radially on the optical disc, and when the optical pickup has arrived at a position at the lead-in side of the optical disc, the sliding member is further slid against the force of the coil spring to move the shutter and mask the objective lens.

    Abstract: A first thin film including at least one transition metal selected from the group consisting of Co, Fe and Ni, and a second thin film including at least one platinum group element selected from the group consisting of Pt and Pd are prepared. Then, a multilayered structure where said first thin film and said second thin film are stacked is formed. Then, the multilayered structure is heated at the same time or after the formation of said multilayered structure, thereby to counter-diffuse constituent elements of said first thin film and said second thin film and alloy said at least one transition metal and said platinum group element.
