Abstract: A disk drive device is provided with a recording disk, a base member, a bearing unit, and a hub member. In a marking step, unbalance information indicating the displacement of the center of gravity of the hub member with respect to the rotation center of the hub member is acquired, and an information mark containing the unbalance information is applied to at least the hub member or the base member. In an installing and adjustment step, the unbalance information is read form the information mark, and the position for installing the recording disk in an outer cylinder part is determined in accordance with the unbalance information so as to install the recording disk on the hub member.

Abstract: An optical pickup angle adjusting mechanism of a beam angle adjusting structure consists of an external screw member and an internal screw part, while the external screw member is formed by integrating a flange engaging part engaging with a chassis to hold the edge of the chassis with two flanges, an external screw portion and a cylindrical press-fit part located between the flange engaging part and the external screw portion and the internal screw part includes a nut fixed to a pickup support part and a press-fit hole formed in the pickup support part coaxially with the nut for receiving the press-fit part in a close contact manner. Thus, a disk drive and a beam angle adjusting structure preventing adjusting screws from jolts can be obtained without increasing the number of components.

Abstract: There is described a method of guiding a machine as it moves relative to a surface, which is preferably the surface of a workpiece on which the machine is working, by selectively magnetizing a layer of magnetic material provided at or close to the surface so as to define a path of movement, producing guidance signals during the relative movement by detecting the selective magnetization, and using the guidance signals to automatically guide the relative movement, so that the defined path is followed. Data other than guidance data may be provided on the layer by selective magnetization.

Abstract: A system for processing digital audio signals. The system includes a digital audio unit configured to provide digital audio data of a first audio track and a second audio track. The first audio track and a second audio track represent different versions of the same piece of music. The system also includes a user control device operable by a user to allow the user to select either a first region or a second region. The digital audio unit is configured to play back audio signals obtained from the first audio track when the first region is selected, and to play back audio signals obtained from the second audio track when the second region is selected.
