Abstract: In a data storage system, stored data is secured using a key-based encryption algorithm. The disclosure provides mechanisms for increasing security of the stored data by storing a unique key used to encrypt and/or decrypt the data in a volatile key storage of a backplane, where power to the volatile key storage is routed through a connection that is closed when a corresponding data storage device is connected to the backplane and open when the corresponding data storage device is disconnected from the backplane.

Abstract: Mechanisms are disclosed for decoupled integration of quantum-safe digital signatures into software applications. Electronic document content is stored, by a software application, in connection with a document store. An application programming interface (API) request is issued to a quantum-safe digital signature service. The API request comprises an identifier associated with the electronic document content and a request to generate a quantum-safe signature associated with the electronic document content. The request to generate a quantum-safe signature of the electronic document content causes the quantum-safe digital signature service to perform several steps. First, the electronic document content is retrieved from the document store. Next, a quantum-safe digital signature data structure is generated. Next, the quantum-safe digital signature data structure is stored to the document store. A signing status update is transmitted to the software application.

Abstract: Systems and methods for implementing optimized host-side device-specific queues for a storage device are described. A host system may implement a host-side queue for a storage device that is optimized using device-specific parameters. When an access request to the storage device is received, the request may be enqueued in an order optimized according to parameters of the storage device. Requests are then sent to the device in an optimized order. Optimization parameters may be provided by the manufacturer and read by the host system from the device, the parameters including physical device geometry and runtime telemetry data. In some embodiments, queue ordering for the host-side queue may be supplied by the storage device.

Abstract: Methods of writing data to a DNA strand by inserting data-encoding oligos or symbols into a DNA backbone. One particular method of synthesizing a DNA strand encoding data includes cleaving a DNA backbone into multiple segments, and pasting a plurality of data-encoding oligo symbols between the multiple segments, with the terminal ends of the segments joining homologous terminal ends of the symbols, resulting in the DNA strand encoding data comprising alternating segments and symbols.

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.

Abstract: Two or more different recording currents are applied to a write coil of a recording head. A first of the two or more currents is a positive current and a second of the two or more currents is a negative current. In response to the application of the two or more different recording currents, a data stream is recorded to regions of a moving continuous magnetic recording medium such that each region has three or more magnetic states. The three or more magnetic states can be read from the continuous magnetic recording medium via a magnetic read transducer to recover the data stream.

Abstract: A disk drive apparatus determines a pattern of bits of a data signal applied to a magnetic write transducer of a heat-assisted magnetic recording apparatus. The magnetic write transducer applies a magnetic field to a recording medium in response to the data signal. A laser power signal is applied to a laser that heats the recording medium while the magnetic field is applied. The laser power signal is modulated based on the pattern of bits. The modulation reduces differences between track widths of recorded marks having different elapsed time values and/or increases a signal-to-noise ratio of the recorded marks having different elapsed time values.
