摘要： A method for achieving a nearly zero net magnetic moment of pinned layers in GMR sensors, such as Co—Fe/Ru/Co—Fe, is described. The method determines a thickness of the first pinned layer which will yield the desired net magnetic moment for the pinned layers. A series of test structures are deposited on a substrate such as glass. The test structures include the seed layers, pinning layers and pinned layers and have varying thicknesses of the first pinned layer. The compositions of the materials and the thicknesses of all of the other films remain constant. The net areal magnetic moment of each test structure is measured and plotted versus the thickness of the first pinned layer. The thickness of the first pinned layer which corresponds most closely to zero net areal magnetic moment is chosen as the design point for the sensor.

摘要： A thin film disk and a disk drive using the thin film disk are described. The disk has an onset layer between the underlayer and the boron containing magnetic layer, for example. The onset layer of the invention is useful because the boron containing magnetic layer material resists being deposited with the C-axis in plane. The onset layer material is selected to promote an in-plane C-axis orientation. When a boron containing magnetic layer is deposited on the onset layer the resulting in-plane PO is improved. The preferred onset layer is of hexagonal closed pack structured material which may be magnetic or nonmagnetic. Materials which are usable for the onset layer include a wide range of pure elements and cobalt alloys such as CoCr, CoPtCr, CoPtCrTa and CoCrB. The onset layer is particularly useful in allowing a ferromagnetic cobalt (Co) alloy containing a relatively high chromium and boron content to be deposited on nonmetallic substrates with the C-axis in the plane of disk without the need for negative bias during the sputtering of the underlayer.

摘要： Magnetic recording media suitable for high density recording are provided by a carbon substrate, a magnetic recording layer, and at least one interlayer therebetween which provides one or more properties beneficial to preventing diffusion, inducing a preferred orientation in the magnetic recording layer and/or promoting adhesion between a carbon substrate and a barium hexaferrite-based magnetic recording layer. Alternatively, the present magnetic recording media may contain two different interlayers, which bar diffusion of carbon atoms from said substrate to said magnetic recording layer, improve adhesion between adjacent layers, induce an orientation in the magnetic recording layer, or any combination thereof. The present recording media are particularly advantageous for perpendicular recording. Processes for producing these magnetic recording media are also provided.

摘要： An energy assisted magnetic recording (EAMR) disk drive comprises a suspension and a slider having a back side, a laser-facing surface, and an air-bearing surface (ABS) opposite the back side. The slider is mounted to the suspension on the back side. The disk drive further comprises an EAMR transducer coupled with the slider, a portion of the EAMR transducer residing in proximity to the ABS and on the laser-facing surface of the slider. The disk drive further comprises a laser coupled with the suspension and having a light emitting surface facing the laser-facing surface of the slider. The laser has an optic axis substantially parallel to the suspension. The laser provides energy substantially along the optic axis and is optically coupled with the EAMR transducer via free space. The EAMR transducer receives the energy from the laser and writes to the media using the energy.

摘要： An anti-parallel pinned sensor is provided with a spacer that increases the anti-parallel coupling strength of the sensor. The anti-parallel pinned sensor is a GMR or TMR sensor having a pure ruthenium or ruthenium alloy spacer. The thickness of the spacer is less than 0.8 nm, preferably between 0.1 and 0.6 nm. The spacer is also annealed in a magnetic field that is 1.5 Tesla or higher, and preferably greater than 5 Tesla. This design yields unexpected results by more than tripling the pinning field over that of typical AP-pinned GMR and TMR sensors that utilize ruthenium spacers which are 0.8 nm thick and annealed in a relatively low magnetic field of approximately 1.3 Tesla.
