摘要： A heat-assisted magnetic recording (HAMR) head has a gas-bearing slider that supports a near-field transducer (NFT) and a main magnetic pole. First heat-sink material is located on the cross-track sides of the main pole and second heat-sink material is located on the cross-track sides of the waveguide. The second heat-sink material may be in contact with the first heat-sink material, and a thermal shunt of high thermal conductivity may interconnect the NFT with the first and second heat-sink material. Heat from the NFT output tip flows to the second heat sink material through the NFT and the thermal shunt. Optically reflective material may be located between the waveguide and the second heat-sink material to improve the optical efficiency of the NFT.

摘要： The present invention relates to a magnetic field sensor apparatus (10) for determining two or three components of a magnetic field. For this purpose, the apparatus (10) comprises at least one Wheatstone bridge (14) with two half-bridges (16), wherein each half-bridge (16) comprises at least two bridge resistors (30), and at least one of the two bridge resistors (30) is a magnetic-field-sensitive resistor (18) with respect to a magnetic field component (34) in an X/Y magnetic field sensor plane (20). Arranged symmetrically between the two magnetic-field-sensitive bridge resistors (18) is a ferromagnetic flux concentration element (22) which generates magnetic field components which are anti-symmetric with respect to a Z magnetic field component (24) oriented perpendicular to the X/Y magnetic field sensor plane (20) and are in the X/Y magnetic field sensor plane (20). A coordinate aspect proposes a method for determining a two-dimensional or three-dimensional orientation of an external magnetic field by means of such a magnetic field sensor apparatus (10).
