20080304181 | METHOD AND APPARATUS FOR PROVIDING AN AIR BEARING WITH HIGHER FLYING HEIGHT FOR LOWER ROTATING SPEED DRIVES - A method and apparatus for improving flying height stability at lower speeds is achieved by an ABS with a channel and pocket.

20090262458 | ABS design for dynamic flying height (DFH) applications - 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. | 10-22-2009 |
20100039732 | ABS design for dynamic flying height (DFH) applications - 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. | 02-18-2010 |
20120092789 | THERMAL FLY HEIGHT CONTROL MAGNETIC RECORDING HEAD HAVING A NOVEL HEATING ELEMENT GEOMETRY - A heating element for use in a thermal fly height control magnetic recording head of a magnetic data recording system.

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.

20120300334 | MAGNETIC HEAD WITH SELF COMPENSATING DUAL THERMAL FLY HEIGHT CONTROL - 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. | 11-29-2012 |

20150213820 | MAGNETIC RECORDING HEAD HAVING THERMAL FLY HEIGHT CONTROL ELEMENT WITH NEAR ZERO MAGNETOMOTIVE FORCE - A magnetic recording head with thermal fly height control, wherein the heating element is configured to eliminate magnetic field effects on the writing pole, which would cause otherwise cause non-symmetric writing or pole erasure. Non-symmetric writing is a phenomenon wherein magnetic writing favors one direction over another, thereby causing a timing shift in recorded data.

The electrically conductive layers are configured so that current flows in opposite directions through each of the electrically conductive layers such that any magnetic field generated by the current flow through one electrically conductive layer is cancelled out by a magnetic field from another electrically conductive layer. | 07-30-2015 |
