A plurality of parallel processing devices such as compression/decompression units can be tied together to sequentially process equal amounts or sets of data from a stream of data. Hardware in the upper level of each device acts as a demultiplexer to control the acceptance of only its set of data to transfer control to permit the next device to accept data and also stores its set for compaction. Essentially identical hardware in the lower half of each device acts as a multiplexer to control the acceptance of its compacted set of data to store the compacted set and to place the compacted set into the original sequence of the stream of data for storage on the tape media. The lower half reverses its role when the compacted set of data is retrieved from the media to act as a demultiplexer for the decode sequence while the upper half acts as a multiplexer to resequence the decompacted sets into its original stream.

A laser module comprising a laser device attached to a heat sink that is configured to provide a relatively low thermal resistance for thermal management of the laser device, and a coefficient of thermal expansion (CTE) that is substantially matched to the CTE of the laser device for reducing stress caused by thermal cycles. The heat sink includes a shell made out of a first material, and an insert situated within the shell and made out of a second material distinct from the first material of the shell. By properly selecting the first and second materials, configuring the overall mass of the shell with respect to the overall mass of the insert, and positioning, arranging, and/or orienting the insert with respect to the laser device, the desired effective thermal resistance and CTE for the heat sink may be achieved. In one embodiment, the shell includes a material, such as copper, or a metal matrix composite such as copper graphite. The insert includes a thermal pyrolytic graphite oriented such that its x-axis extends substantially parallel to the longitudinal axis of the laser device, and its y-axis extends substantially perpendicular to the laser device.

A laser module comprising a laser device attached to a heat sink that is configured to provide a relatively low thermal resistance for thermal management of the laser device, and a coefficient of thermal expansion (CTE) that is substantially matched to the CTE of the laser device for reducing stress caused by thermal cycles and bonding. In one embodiment, the heat sink comprises a substrate made out of a first material, and including one or more via holes filled with a second material distinct from the first material of the substrate. By properly selecting the first and second materials, configuring the overall mass of the substrate with respect to the overall mass of the filled via holes, and positioning and arranging the filled via holes with respect to the laser device, the desired effective thermal resistance and CTE for the heat sink may be achieved. In another embodiment, the laser module comprises a laser device attached to a submount, which is, in turn, attached to a heat sink. In this embodiment, the submount is configured as the heat sink discussed above.

Hardware in the upper level of each device acts as a demultiplexer to control the acceptance of only its set of data to transfer control to permit the next device to accept data and also stores its set for compaction. Essentially identical hardware in the lower half of each device acts as a multiplexer to control the acceptance of its compacted set of data to store the compacted set and to place the compacted set into the original sequence of the stream of data for storage on the tape media. A data integrity system provides a Cyclic Redundancy Check on the data before and after each section of the process. The compacted data is decompacted immediately after compaction as a read back check to verify that the compacted data can be reconstructed when retrieved. CRC codes are stored on the media with the compacted data and are used to verify the compacted data retrieved from the media.
