摘要:
The invention provides an optical semiconductor device which comprises: an optical semiconductor element; a first resin layer encapsulating the optical semiconductor element and comprising a first resin and light-scattering particles; and one or more resin layers sequentially encapsulating the first resin layer and each comprising a resin having a lower refractive index than the first resin. In an embodiment where the optical semiconductor device has a plurality of resin layers over the first resin layer, the plurality of resin layers are disposed such that the refractive indexes of the constituting resins sequentially decrease toward the outermost resin layer.
摘要:
In a method for reproducing multimedia data recorded over plural optical disks using an optical disk library unit having at least one optical disk drive, during reading and reproduction of the multimedia data recorded in one of the optical disks, multimedia data from the optical disk is prefetched by an amount larger than the amount equivalent to the time required for exchange of the optical disks. The prefetched data is temporarily stored, and when the optical disk is exchanged for the next optical disk, the temporarily stored data is read and reproduced.
