摘要： The invention generally relates to hard disk drives with a disk and a read/write head, and methods for preventing contact between the disk and the read/write head. The hard disk drive includes a z-axis actuator configured to control movement of the read/write head, and to prevent contact between the read/write head and the disk, based on signals from a controller that indicate when the distance between the read/write head and the disk are outside a predetermined range, such as between 0 and 10.0 nm.

摘要： A magnetic tape recording module having electrical lapping guides located within and adjacent to an array of magnetic read/write elements. Electrical leads connected with the electrical lapping guides are buried deep within the head build, close to the substrate so that they can pass beneath the electrical leads of the read/write elements without any capacitive coupling between the electrical lapping guide leads and the read/write element leads. The presence of the electrical lapping guides within and adjacent to the read/write element leads provides much more accurate control of read/write element stripe height during lapping.

摘要： An apparatus and associated methodology contemplating a slider body defining longitudinal extents at a leading end and a trailing end. A fluid bearing surface is formed in part by a side rail extending substantially longitudinally along the slider body and joined to a cross rail extending substantially laterally along the slider body. The side rail and the cross rail define at least a portion of a positive pressure recess. A vent is defined in the fluid bearing surface that is in fluid communication with ambient pressure fluid on one side of the side rail but is not in fluid communication with the positive pressure recess on the other side of the side rail.

摘要： A control mechanism may control the height and/or position of a read/write head configured to interact with a rotating information storage surface. A computation unit may compute a detected topography from gap measurements using a dynamic filter including a model of read/write head dynamics. A sensor may detect gap measurements of a side read/write track while the read/write head is interacting with a current read/write track. A memory may store the detected topography. The control mechanism may adjust the height of the read/write head based on the detected and/or stored topography. The control mechanism may be a reactionless control mechanism configured to apply a counterforce to offset movements of the read/write head and/or a slider.

摘要： A recording head for use in magnetic storage devices is disclosed. The recording head includes a transducer that is bi-directionally movable with respect to a surface of the magnetic storage medium, thereby enabling improved positioning of the transducer during recording head read and write operations. Various structures are disclosed to bi-directionally actuate the recording head transducer. In one embodiment, an interleaver assembly having a plurality of flexure assemblies employs a motor including magnetic portions for selective, bi-directional actuation. In another embodiment, electrostatic charges are employed in the flexure assemblies for selective actuation. In yet another embodiment, piezoelectric elements are included to provide for selective actuation.

摘要： A slider having an improved atmospheric pressure variation characteristic can be provided by ensuring the desired amount of inflow of air flowing to the air bearing surface in a region where it is difficult to ensure the desired air inflow amount, e.g., a region where the slider/disk relative speed is low or a region where the area of the air bearing surface is small by forming a groove configuration surface in a specified shape. In the negative pressure utilization type slider, a groove configuration surface lower in height than an air in flow surface is formed between the disk inner peripheral end and the disk outer peripheral end of the air inflow surface in the air flow incoming end side of a pressure generating surface, separately from a negative pressure generating surface.
