摘要： A slider for supporting a transducing head proximate to a rotating disc. The slider has a slider body having a disc opposing face and a longitudinal axis. The disc opposing face is bounded by a leading edge, a trailing edge, and first and second side edges. An air bearing surface is defined on the disc opposing face with the air bearing surface having at least one pad located behind the leading edge. A cavity is positioned on the disc opposing face and the cavity is recessed from the air bearing surface at a cavity depth. At least a portion of the cavity precedes the pad. A funnel directs airflow within the cavity from the leading edge to the pad.

摘要： A disc head slider includes a slider body having a disc-opposing face with leading and trailing slider edges, a slider length measured between the leading and trailing slider edges, a bearing surface, a recessed area, an inlet and a convergent channel. The recessed area is recessed from the bearing surface. The inlet has a leading channel end, which is open to air flow from the leading slider edge, channel side walls and a trailing channel end. The convergent channel has a leading channel end, which is open to fluid flow from the inlet, channel side walls and a trailing channel end, which is closed to the fluid flow. The trailing channel end of the convergent channel is located along the slider length rearward of at least a portion of the recessed area and forward of at least a portion of the bearing surface.

摘要： A disc drive assembly includes a housing, a disc, an actuator, a ramp and a slider. The ramp is positioned along an edge of the disc to engage a portion of the actuator when the actuator is in a parked position. The slider is supported over the disc by the actuator and includes first and second elongated rails. Each rail has a leading bearing surface, a trailing bearing surface, and a recessed area extending between the leading and trailing bearing surfaces. First and second convergent channels are recessed within the trailing bearing surfaces of the first and second rails, respectively. Each channel includes a leading channel end open to fluid flow from the respective recessed area, non-divergent channel side walls and a trailing channel end closed to the fluid flow and forward of a localized region of the respective trailing bearing surface.

摘要： A disc head slider includes a slider body having a disc-facing surface, a recessed area positioned on the disc-facing surface, and a raised rail positioned on the disc-facing surface adjacent the recessed area. The raised rail includes a bearing surface and a recessed step surface which is recessed from the bearing surface and is raised from the recessed area. A plurality of bearing pads are formed on the recessed step surface and have upper surfaces that together define the bearing surface. A non-bearing pad is formed on the recessed step surface and has an upper surface, which is generally coplanar with the bearing surface, and a pointed leading pad edge.

摘要： A method and system for improving performance in a disc drive using a genetic algorithm. Chromosomes of parameter settings are loaded into disc drive components and one or more metrics are monitored that respond to variations in the parameter settings. A fitness for each chromosome is obtained as a function of the one or more metrics. The chromosomes of settings are mated and adapted over time based on the fitness of each chromosome. Parameters within each chromosome vary by random selection based on the fitness of the chromosome.

摘要： A fly height detector apparatus and associated method for detecting the fly height of a read/write head spatially disposed from a data storage surface during a data transfer operation. The fly height detector apparatus comprises a receiver circuit measuring the frequency of the read/write head; a perturbation deliverable to the gap between the read/write head and the data storage surface to invoke a dynamic response in the read/write head; and a processor circuit responsive to the receiver circuit to derive a fly height in relation to the dynamic response frequency. The processor circuit comprises a memory in which is stored a numerical model describing a functional interrelationship between the fly height and the read/write head frequency.
