    摘要： In certain embodiments, a tunneling magneto-resistive (TMR) sensor includes a sensor stack positioned between a seed layer and a cap layer. The seed layer includes a first buffer layer that includes a non-magnetic nickel alloy. In certain embodiments, a sensor stack includes a top and bottom shield and a seed layer positioned adjacent to the bottom shield. The seed layer has a first buffer layer that includes a nickel alloy.

    摘要： An apparatus comprises a head transducer and a resistive temperature sensor provided on the head transducer. The resistive temperature sensor comprises a first layer comprising a conductive material and having a temperature coefficient of resistance (TCR) and a second layer comprising at least one of a specular layer and a seed layer. A method is disclosed to fabricate such sensor with a laminated thin film structure to achieve a large TCR. The thicknesses of various layers in the laminated thin film are in the range of few to a few tens of nanometers. The combinations of the deliberately optimized multilayer thin film structures and the fabrication of such films at the elevated temperatures are disclosed to obtain the large TCR.

    摘要： A write head including a bearing surface and a write pole having a front surface that forms a portion of the bearing surface. The front surface has a leading edge, a trailing edge and side edges connecting the leading and trailing edges. The write head also includes side shields proximate to the side edges of the write pole, and a trailing shield over the write pole and the side shields. A trailing shield-write pole gap is present between the trailing edge and the trailing shield, and a trailing shield-side shield gap is present between the trailing shield and the side shields. The trailing shield-shield shield gap is substantially less than the trailing shield-write pole gap.

    摘要： A data writer may be constructed and operated as part of a data storage device. The data writer can be positioned proximal a data storage medium. The data writer may have a write pole positioned adjacent a writer coil with the writer coil having a plurality of turns. A controller that is connected to each turn can be adapted to selectively activate less than all the coil turns in response to the data writer being positioned over a first portion of a data storage medium and selectively activate all of the coil turns in response to the data writer being positioned over a second portion of the data storage medium.

    摘要： Implementations described and claimed herein includes a storage device comprising a plurality of readers, including a first subset of readers configured to read a first subset of tracks and a second subset of readers configured to read a second subset of tracks, the first subset of tracks being wider than the second subset of tracks. In another implementation, the readers in the first subset of readers are wider than the readers in the second subset of readers. The wider readers may be configured to recover servo information and the narrow readers may be configured to recover data information. The storage devices may include two-dimensional magnetic recording, conventional perpendicular magnetic recording, shingled magnetic recording, multi-sensor magnetic recording, and interlaced magnetic recording.
