摘要： A method and apparatus for improving flying height stability in a small form factor hard disk drive that typically moves at lower speeds is achieved by a slider having an ABS with an air channel and pocket. The air channel and pocket are configured to increase the amount of aerodynamic lift provided by normally smaller amounts of intake air at the inner diameter of the rotating disk and, thereby, to achieve a desired flying height profile.

摘要： A magnetic head for data recording having a pair of heating elements that self regulate in response to temperature to distribute heat for thermal actuation. The head includes a first heating element located adjacent to the read sensor and away from the writer, and a second heating element located adjacent to the writer. The first and second heating elements have different coefficients of thermal resistance that cause the heating of the second heating element to increase relative to that of the first heating element when the overall temperature increases or when power provided by a power source increases. There, thereby prevents the read sensor from extending too much and possibly contacting the disk.

摘要： A heating element for use in a thermal fly height control magnetic recording head of a magnetic data recording system. The heating element has a centrally disposed portion with a straight front edge that is recessed by a substantially constant distance, and has first and second side portions that taper away from the air bearing surface. The side portions preferably taper away from the air bearing surface by an angle of 20 to 45 degrees. The center portion of the front edge is spaced from the air bearing surface by a distance D and has a width W, such that W is 1.5 to 2.5 (or about 2) times D. D is typically 2-6 um to have good heater efficiency while being large enough to not over heat the heater. The heating element has an overall width WW and a overall depth HH from the air bearing surface such that WW is 1.5-2.5 (or about 2) times HH.

摘要： An embodiment of the present invention is an ABS design with a pitch ladder feature. This embodiment has an air flow squeezing channel which consists of one airflow blocker and three etching steps. The airflow blocker can be used to limit the incoming air flow from the leading edge of the ABS. Additionally, the embodiment contains an air channel that reduces altitude sensitivity by channeling air at the inner diameter into a sub-ambient pressure cavity.

摘要： A DFH (Dynamic Flying Height) type slider ABS design has a stable flying height and a DFH efficiency that is uniform across the entire disk surface. These properties are a result of embedding the read/write head and heater in a trapezoidally bridged micro-pad having a very small surface area. The micro-pad is surrounded by a wing-like structure that projects from a central rail in the ABS and the micro pad is connected to an inner edge of that structure by a bridge having a trapezoidal shape. The trapezoidal shape responds effectively to variations in air flow direction and pressure point as the slider moves across the disk surface and, as a result, provides the uniform DFH efficiency. At the same time, the projecting wings and adjacent topology help to direct the airflow around the micro-pad and provide the stable flying height.
摘要翻译： DFH（动态飞行高度）型滑块ABS设计具有稳定的飞行高度和整个磁盘表面均匀的DFH效率。这些性质是将读/写头和加热器嵌入具有非常小的表面积的梯形桥接微垫中的结果。微垫被由ABS中的中心轨道突出的翼状结构包围，并且微垫通过具有梯形形状的桥连接到该结构的内边缘。当滑块越过盘表面时，梯形形状有效地响应于空气流动方向和压力点的变化，结果提供了均匀的DFH效率。同时，突出的机翼和相邻的拓扑结构有助于引导微型焊盘周围的气流，并提供稳定的飞行高度。

摘要： A DFH (Dynamic Flying Height) type slider ABS design has significantly improved DFH efficiency and a decreased sensitivity of flying height to both ambient conditions and disk surface variations. This is a result of embedding the read/write head and heater in a micro-pad having a very small surface area. The micro-pad is surrounded by a wing-like structure that projects from a central rail in the ABS. The micro-pad is separated from the central rail by a surrounding trench whose depth can be varied to tune the DFH efficiency. The small surface area of the micro-pad reduces the air pressure at the read/write head and the projecting wings and adjacent topology help to direct the airflow around the micro-pad.
