A concave mirror substance 1 constituting a reflector is composed of a base material having a high thermal conductivity such as aluminum etc. An infrared-to-heat converting layer 2 is film-formed by anodizing the substrate formed of aluminum etc., so as to absorb light in a wavelength range which passes through a visible light reflecting layer 4 and convert it into heat. A gloss-forming buffer layer 3 is film-formed by calcining Si resin or polyimide resin over the inner side (the light source-side surface) of infrared-to-heat converting layer 2 at high temperatures, so as to buffer the two layers in a manner that does not allow infrared-to-heat converting layer 2 and visible light reflecting layer 4 to be in direct contact with each other, and so as to reduce the influence of projections and indentations present on infrared-to-heat converting layer 2 and smoothen the light source-side surface of visible light reflecting layer 4. In this way, it is possible to suppress performance degradation by efficient discharge of heat by converting light into heat and by alleviating thermal stress and strain due to the difference in expansion coefficient between components, and it is also possible to achieve reduction in cost, miniaturization and weight reduction.

A large number of pattern elements stands upright on an upper surface of a substrate. After the upper surface of the substrate has been processed using a processing liquid, liquid filling processing for filling the upper surface with a filler solution is performed, in which the filler solution having a viscosity of three centipoises or more is applied to a central part of the upper surface. Then, by rotating the substrate at 1000 revolutions per minute or less, the processing solution adhering to the entire upper surface is replaced by the filler solution, and a solution layer of a predetermined thickness is formed. In this way, making the viscosity of the filler solution relatively high and making the centrifugal force acting at the time of rotating the substrate relatively low suppresses deformation of the pattern elements at the time of filling with a filler that uses the filler solution.

Embodiments of the present invention help to suppress performance degradation in an actuator of a disk drive device when attaching a damping member to a single surface of an arm. According to one embodiment, in a HDD a damping member is attached to a single surface of an arm. A shape of an inner arm is asymmetric with the center position between disks.

This suppresses deformation of the vibration mode in the case that the damping member is attached to the single surface of the arm.
