    Abstract: At least one laser input current is applied to a laser in a heat assisted magnetic recording device. Laser output power of the laser is measured at the at least one applied laser current. A relationship is characterized amongst temperature, applied laser input current and laser output power. Laser current is set to an optimal laser current as determined at manufacturing. A metric of recording performance is measured to determine if the relationship is acceptable.

    Abstract: A transducer is configured to interact with a magnetic storage medium, a first channel comprises a first sensor and first circuitry configured to adjust a plurality of first channel parameters, and a second channel comprises a second sensor and second circuitry configured to adjust a plurality of second channel parameters. The first and second channel parameters are independently adjustable by the first and second circuitry, respectively. A detector is coupled to the first and second channels, and configured to detect a head-medium interface event.

    Abstract: A system for DNA gene assembly that utilizes a DNA symbol library and a DNA linker library. The symbol library has a number of DNA symbols each having a first overhanging end and a second overhanging end different than and non-complimentary to the first end, the first and second ends being the same nucleotides for each DNA symbol. The linker library has pairs of DNA linkers, a first linker of a pair having a first end and a second end and a second linker of the pair having a first end and a second end, the first end of the first linker being the same nucleotides for each first linker and the second end of the second linker being the same nucleotides for each second linker, wherein the second end of the first linker and the first end of the second linker have complementary nucleotides. The first linker joins to the first end of a DNA symbol and the second linker joins to the second end of another DNA symbol.
