Abstract: A system and method for adjusting the alignment and location of a magnet. A first actuator exerts a first applied force to urge the magnet in a first axial direction and a first biasing device exerts a first opposing force. The first applied force and opposing forces are modulated relative to each other to position the magnet at a lateral location. A second actuator exerts a second applied force to urge the magnet in a first angular direction about a pivot axis and a second biasing device exerts a second opposing force. The second applied and opposing forces are modulated relative to each other to position the magnet at a select angular orientation relative to the magnet holder. The magnet is secured to the magnet holder after positioning. The magnet can also be rotated about its geometric centerline to position its magnetic axis.

Abstract: This disclosure describes, in part, techniques and systems for accurately and efficiently updating applications stored on client computing devices. In some instances, the systems and techniques receive an update from an application developer, but rather than send the update directly to a client computing device that operates the application, the systems and techniques determine one or more difference between the current update and an update previously sent to the client computing device and, thereafter, send a “diff file” indicative of these differences to the client computing device. The client computing device may then use the diff file and the previously received update to re-create the new update. Thus, the systems and techniques are able to update client computing devices while limiting the amount of data sent over a network to these devices.

In one example, an interlayer alloy is provided that includes tungsten (W) along with Cobalt (Co), Chromium (Cr), and Ruthenium (Ru). The atomic percentages of W and Ru within the interlayer are selected so that the amount lattice mismatch between the interlayer and its adjacent layers is below a preselected amount, such as below 3% as quantified by d-spacing. In some examples, the atomic percentage of Ru is greater than 25% and the atomic percentage of W is 2-10%. Methods of fabricating the magnetic recording media are also provided.

Abstract: Aspects of a data environment, such as the creation, provisioning, and management of data stores and instances, are managed using a separate control environment. A user can call into an externally-facing interface of the control environment, the call being analyzed to determine actions to be performed in the data environment. A monitoring component of the control plane also can periodically communicate with the data environment to determine any necessary actions to be performed, such as to recover from faults or events in the data environment. A workflow can be instantiated that includes tasks necessary to perform the action. For each task, state information can be passed to a component in the data environment operable to perform the task, until all tasks for an action are completed. Data in the data environment can be accessed directly using an externally-facing interface of the data environment, without accessing the control plane.

Abstract: Systems and methods for dynamic maximum transmission unit determination are disclosed. For example, one or more triggering events may be detected to initiate determining whether to adjust transmission unit sizing for data transmission between devices. Received signal strength indicator (RSSI) values may be exchanged between the devices and those RSSI values may be utilized to determine a strength of a communication signal between devices. When the RSSI values are low, the communication signal strength may be weak and the devices may adjust the transmission unit size to be larger. In other examples when the RSSI values are high, the communication signal strength may be strong and the devices may adjust the transmission unit size to be smaller.

Abstract: A data storage device including, in one implementation, a non-volatile memory device including a memory block that includes a plurality of memory dies and a controller that is coupled to the non-volatile memory device and that allocates power to non-memory components based on a determined usage of the memory dies. The controller is configured to monitor a utilization of the plurality of memory dies, determine a utilization state of the plurality of memory dies, and calculate an amount of available power allocated to the plurality of memory dies in response to determining that the plurality of memory dies are in a low utilization state. The controller is also configured to determine whether the amount of available power is above a predetermined threshold, and reallocate the available power to one or more components within the data storage device in response to determining that the amount of available power is above the predetermined threshold.

Abstract: Technologies are disclosed for generating resources within a secured network. When a user from an outside network wants to perform actions involving resources of a secured network, the user simply indicates the actions to perform within a resource file. Upon specifying the actions to perform, the requested actions specified in the resource file are securely transferred to the secured network where a cleared user of the secured network may approve/reject the actions to perform. In some cases, the cleared user may view the actions within a graphical user interface (GUI) and approve/reject the requested actions. The approved actions are then executed within the secured network. Results obtained from executing the approved actions are transferred to the user of the outside network without the user having to message, or call, the cleared user of the secured network.

Abstract: A read head includes a permanent magnet (PM) layer formed up to 100 nm behind a free layer where PM layer magnetization may be initialized in a direction that adjusts free layer (FL) bias point, and shifts sensor asymmetry (Asym) closer to 0% for individual heads at slider or Head Gimbal Assembly level to provide a significant improvement in device yield. Asym is adjusted using different initialization schemes and initialization directions. With individual heads, initialization direction is selected based on a prior measurement of asymmetry. The PM layer is CoPt or CoCrPt and has coercivity from 500 Oersted to 1000 Oersted. The PM layer may have a width equal to the FL, or a width equal to the cross-track distance between outer sides of the longitudinal bias layers. In another embodiment, the PM layer adjoins a backside of the top shield.
