  • Lapping device with lapping control feature and method
    Patent number: 9321143
    Abstract: A head structure for a lapping assembly including a lapping control feature is disclosed. The lapping control feature includes a raised contact surface elevated from a front surface of the head structure of the lapping assembly. A relative position of the workpiece and raised contact surface are aligned to control workpiece thickness and other lapping parameters. In illustrated embodiments, the relative position of the workpiece and raised contact surface are aligned via an adjustment mechanism on the head structure. In illustrated embodiments, the adjustment mechanism is configured to adjust a position of the workpiece relative to the raised contact surface.

  • Methods and devices to control write pole height in recording heads
    Patent number: 9036298
    Abstract: Recording heads for data storage systems are provided. Recording heads illustratively include a write pole, a bumper, a dielectric layer, and a surface. In some embodiments, a portion of the surface includes portions of the write pole, bumper, and dielectric layer. The write pole, bumper, and dielectric layer are illustratively made from materials that have polishing rates. In some embodiments, the polishing rate for the write pole material is more similar to the polishing rate for the bumper material than it is to the polishing rate for the dielectric layer material.

  • Lapping carrier having hard and soft properties, and methods
    Patent number: 9017139
    Abstract: A carrier for a slider row bar for a lapping process. The carrier has a mounting structure comprising a material configured to have a first modulus of at least 1,000,000 Pa at a first period of time and a second modulus of 500 Pa to 500,000 Pa at a second period of time subsequent to the first period. The change from the first modulus to the second modulus is due to an external stimulus on the material.
