摘要： A heat assisted magnetic recording (HAMR) writer is described. The HAMR writer is coupled with a laser that provides energy having a first polarization state. The HAMR writer has an air-bearing surface (ABS) configured to reside in proximity to a media during use, a plurality of waveguides, a main pole and at least one coil. The main pole writes to the media and is energized by the coil(s). The waveguides receive the energy from the laser and direct the energy toward the ABS. The waveguides include an input waveguide and an output waveguide. The input waveguide is configured to carry light having the first polarization state. The output waveguide is configured to carry light having a second polarization state different from the first polarization state. The waveguides are optically coupled and configured to transfer the energy from the first polarization state to the second polarization state.

摘要： A magnetic apparatus has a media-facing surface (MFS), a pole, a write gap at the MFS, a trailing shield, coil(s) and a nonmagnetic refill material. The pole includes a pole tip proximate to the MFS. The trailing shield includes a pedestal and a recessed portion. The pedestal occupies a portion of the MFS. The recessed portion has a front surface at an acute angle from the MFS and is recessed from the MFS by a distance of not more than 0.8 micrometers. The write gap is between the pedestal and the pole tip. The coil(s) energize the pole and have at least one turn. The coil(s) are between the recessed portion of the trailing shield and the pole. The trailing shield is between the nonmagnetic refill material and the pole. A portion of the nonmagnetic refill material is between the recessed portion and the MFS.

摘要： A method provides a magnetic read apparatus. A sensor stack is deposited. The read sensor is defined from the stack such that the sensor has sides forming a junction angle of 75 degrees-105 degrees from a sensor bottom. Defining the sensor includes performing a first ion mill at a first angle and a first energy and performing a second ion mill at a second angle greater than the first angle and at a second energy less than the first energy. The first angle is 5 degrees-30 degrees from normal to the top surface. After the first ion mill, less than half of the stack's bottom layer depth remains unmilled. Magnetic bias structure(s) adjacent to the sides may be formed. The magnetic bias structure(s) include a side shielding material having at least one of the saturation magnetization greater than 800 emu/cm3 and an exchange length less than five nanometers.

摘要： A method and system provide a magnetic transducer having an air-bearing surface (ABS). The method includes providing a first shield, a first read sensor, an antiferromagnetically coupled (AFC) shield that includes an antiferromagnet, a second read sensor and a second shield. The read sensors are between the first and second shields. The AFC shield is between the read sensors. An optional anneal for the first shield is in a magnetic field at a first angle from the ABS. Anneals for the first and second read sensors are in magnetic fields in desired first and second read sensor bias directions. The AFC shield anneal is in a magnetic field at a third angle from the ABS. The second shield anneal is in a magnetic field at a fifth angle from the ABS. The fifth angle is selected based on a thickness and a desired AFC shield bias direction for the antiferromagnet.

摘要： A heat assisted magnetic recording (HAMR) write apparatus has a media-facing surface (MFS) and is coupled with a laser that provides energy. The HAMR write apparatus includes a waveguide, a near-field transducer (NFT), a pole and coil(s) for energizing the pole. The waveguide is optically coupled with the laser and directs a first portion of the energy toward the MFS. The NFT is optically coupled with the waveguide. The pole writes to a region of the media and includes a pole tip. A first portion of the pole tip is at the MFS and is separated from the NFT in a down track direction. A second portion of the pole tip is recessed from the MFS and between the first portion and the NFT.
