摘要： A data storage device receives a write data command and data. The data is stored in a buffer of the data storage device. The data storage device issues a command complete status indication. After the command complete status indication is issued, the data are stored in a primary memory of the data storage device. The primary memory comprises a first type of non-volatile memory and the buffer comprises a second type of non-volatile memory that is different from the first type of non-volatile memory.

摘要： An apparatus of the present disclosure includes a controller coupled to a read/write head wherein the controller is configured to perform various operations. More specifically, the controller is configured to monitor an operational parameter of the read/write head and to detect a fault based on the operational parameter. The fault indicates that a write enabling energy source is malfunctioning during a write operation. The controller is additionally configured, in response to the fault, to take remedial action to protect data associated with the write operation.

摘要： Torn write mitigation circuitry determines if a write operation to memory is in progress at or about a time of power loss. In response to the write operation being in progress at or about the time of the power loss, the torn write mitigation circuitry causes torn write data and metadata to be stored to a non-volatile cache. The torn write data comprise data left in a degraded or uncorrectable state as a result of the loss of power. The metadata describe the torn write data.

摘要： First and second data representation are stored in first and second blocks of a non-volatile, solid-state memory. The first and second blocks share series-connected bit lines. The first and second blocks are selected and other blocks of the non-volatile, solid-state memory that share the bit lines are deselected. The bit lines are read to determine a combination of the first and second data representations. The combination may include a union or an intersection.

摘要： Apparatus for generating supply voltages in a data storage device. In some embodiments, the apparatus includes a data transducer adjacent a rotatable magnetic recording medium, the data transducer having a write coil and an electromagnetic source for thermally assisted recording by the write coil. A preamplifier/driver circuit (preamp) has a write driver adapted to supply write currents to the write coil and a source driver adapted to supply source voltage to the electromagnetic source. A voltage regulation circuit applies a first positive supply voltage to the write driver and a different, second positive supply voltage to the source driver.

摘要： A method of stereoscopic mapping an underwater location includes determining a relative position and relative distance between two separate sensors on separate underwater platforms. Each of the two separate sensors scans a same underwater feature from its respective determined relative position. A stereoscopic image of the underwater feature is created from the two scanned images.

摘要： An apparatus includes a heat pipe with a fluid path. A first part of the fluid path is thermally coupled to a first region of a higher temperature and a second part of the fluid path thermally is coupled to a second region of a lower temperature. A difference between the higher temperature and the lower temperature induces a flow of a magnetic fluid in the fluid path. A switchable magnetic device is magnetically coupled to the fluid path. Activation of the switchable magnetic device reduces the flow of the magnetic fluid in the fluid path, which reduces heat transfer from the first region to the second region.
