Abstract: A method in a server device for a source agnostic model is described. The method includes receiving from a client device associated with a subscriber account a selection of a content item. The method also includes selecting a content source that includes the content item in the selection of a content item, wherein the content source is selected based on a priority configuration of content sources in a configuration store, and wherein the priority configuration of content sources prioritizes content sources based at least on the location of the client device and the format that the selected content item stored at each content store is in.

Abstract: The invention provides an optical head device in which the influence of mechanical vibration generated at resonance frequencies of high orders (second and higher orders) can be eliminated and an optical recording/reproducing apparatus utilizing the same. Sidewalls are formed from both ends of a sidewall constituting the top side of a trapezoidal contour of a lens holder portion, the sidewalls extending in the form of a fan to define a predetermined angle between them. A damping system includes a weight in the form of a metal thin plate and a visco-elastic adhesive for bonding the weight to the sidewalls. The visco-elastic adhesive transfers vibration of the lens holder in the direction of an optical axis of an objective lens to the weight and has a viscous damping property which damps vibration of the weight in the direction of the optical axis.
