    Abstract: A method for calibrating a hard drive having a heat-assisted magnetic recording head is provided. The method includes performing, across an increasing temperature ramp, a first set of write/read operations using the head, performing, across a decreasing temperature ramp, a second set of write/read operations using the head, generating performance data associated with the head based on the first set of write/read operations and the second set of write/read operations, calculating a comparison value based on the performance data associated with the head and performance data associated with a plurality of heads, and adjusting an operating parameter value of the head based on the comparison value exceeding a threshold, the adjusted operating parameter reducing a likelihood that a laser of the head will exhibit write instability.

  • Patent number: 12260117
    Abstract: Apparatus and method for executing controller memory buffer (CMB) based data transfer commands in a distributed data processing environment. In some embodiments, a storage device having a device controller and a main non-volatile memory (NVM) is coupled to a client device via an interface. The client device respectively issues normal data transfer commands and bypass data transfer commands to the storage device. The normal data transfer commands include read and write commands that result in transfer of data between the NVM and the client device using a normal data path through the storage device. The bypass data transfer commands involve an allocated CMB of the storage device directly controlled and accessed by the client device. In this way, write data are directly placed into the CMB for writing to the NVM, and readback data from the NVM are directly recovered from the CMB by the client device.

  • Patent number: 12190922
    Abstract: A method involves forming a recording head that comprises a waveguide, a write pole, and a near-field transducer proximate the write pole. The near-field transducer has an extended portion extending towards a surface of the recording head and operable to direct plasmons to a recording medium. The surface of the recording head is lapped to form a lapped surface. A resist or hardmask is patterned on the lapped surface in a region that encompasses the extended portion. The lapped surface is etched with the resist or hardmask pattern to form a media-facing surface such that the extended portion protrudes beyond the media-facing surface by a first distance, and the resist or hardmask is removed.

  • Patent number: 12116689
    Abstract: The slow speed of conventional selective electroplating and L-PED (and further requirement of a series of masks in the case of selective electroplating) necessary to generate a metallic three-dimensional object makes conventional selective electroplating and L-PED not viable for mass manufacturing metallic three-dimensional objects. The presently disclosed technology generally utilizes electroplating and L-PED technologies with a screen electroplating process. The screen electroplating process disclosed herein is capable of achieving a faster throughput and a lower workpiece temperature than traditional 3D printing processes can provide, particularly traditional metal 3D printing processes. As a result, the presently disclosed screen electroplating process is able to achieve much faster results in printing a complex three-dimensional metallic structure using electroplating.
