Abstract: An etching solution for etching away a metal layer from a substrate includes a hydrogen-containing compound that dissolves the metal layer while developing hydrogen; and a nitrosubstituted organic compound having a nitro group which is easily hydratable and which has at least a 1/3 nitro group equivalent per mole of the hydrogen developed by reaction between the hydrogen-containing compound and the metal layer until the metal layer is dissolved completely. A method for etching employs the etching solution into which the substrate is immersed. The process of preventing the release of hydrogen gas during the etching away of a metal layer from a substrate is taught and includes employing an etching solution containing one of an acid or a highly basic metal hydroxide; and adding to the etching solution an organic nitro compound which is soluble in water and which is easily hydratable.

Abstract: A disc unit includes a control circuit board engaged with a base body of the disc unit, and a shield cover for noise shielding. The shield cover is also used for preventing the separation of mounting tabs extending from the circuit board and the base body by pressing them to hold the circuit board on the base body. Furthermore the shield cover is used as reinforcement for preventing the base body from distorting. With such a structure, the control circuit board is held on the base body by pressure of the shield cover so that multiple fixing members such as screws for fixing the control circuit board can be omitted. Further, since the base body is reinforced by the shield cover, the prevention of distortion of the base body is performed without increasing the thickness of the unit. The disc unit also includes a direct drive motor having a rotor yoke which receives the disc, which rotates a spindle shaft that engages the central opening of the disc.
