The first adhesive track is formed in a region of an externally accessible seam between the substrate layer and the carrier, and the second adhesive track is formed parallel to the first adhesive track in an inner region of the bearing areas that face one another.

Abstract: A CAM device combines a folded bit line architecture with a standard six transistor DRAM based CAM cell and includes a sensing scheme where the active and reference bit lines being sensed are each from the same memory array of the CAM device. Noise present in one array therefore appears as common mode noise in both the active and reference bit lines, thereby permitting the sensing operation to be performed accurately even in the presence of increased noise.

Abstract: A content addressable memory (CAM) device includes a plurality of entries each having an associated counter. When a CAM entry matches a search word stored in the comparand register of the CAM device, the matching entry's counter may be incremented. Alternatively, if there are multiple matching entries, in some instances only one matching entry has its counter incremented. The counter value can be written or read as part of either the least significant or most significant bits of the CAM entry.

Abstract: A polarizing beam splitter for separating an upstream beam from a downstream beam according to the polarization of an incident beam is provided between first and second light sources emitting laser beams at respective wavelength and an objective lens. A phase plate for providing a phase difference to a beam incident on the polarizing beam splitter is provided between the polarizing beam splitter and the light sources. A portion of the laser beam incident on the polarizing beam splitter is reflected by the polarizing beam splitter and caused to be incident on a photo-detecting unit, so as to prevent an unnecessary portion of the laser beam is incident on the photo-detecting unit. According to the invention, the laser beam is used efficiently and the cost of fabricating an optical disk apparatus is reduced by eliminating a need for a gain controlling circuit in the photo-detecting unit.

Abstract: A storage element pending command queue prioritization system using multiple pending queues each assigned to a particular RAID command type. Pending commands from each of the queues are organized in such a way that lower priority commands are guaranteed a fixed amount of storage element bandwidth. Storage element throughput is optimized by limiting higher priority commands to a maximum service level and processing lower priority requests with the added storage element bandwidth, allowing lower priority requests to exceed their minimum service levels.
