摘要： A write head structure for perpendicular recording having a pole tip integrated into the metal film surrounding a C aperture near field light source is disclosed. The close proximity of the pole tip to the light source enables more precise location of data cells written into the magnetic media, through the use of dual gradient thermally assisted recording. In dual gradient recording, data is fixed by the effect of both a thermal gradient, which affects the coercivity of the magnetic media, combined with a magnetic field gradient imposed by the pole tip.

摘要： A process for forming a plurality of sliders for use in thermally-assisted recording (TAR) disk drives includes a wafer-level process for forming a plurality of aperture structures, and optionally abutting optical channels, on a wafer surface prior to cutting the wafer into individual sliders. The wafer has a generally planar surface arranged into a plurality of rectangularly-shaped regions. In each rectangular region a first metal layer is deposited on the wafer surface, followed by a layer of radiation-transmissive aperture material, which is then lithographically patterned to define the width of the aperture, the aperture width being parallel to the length of the rectangularly-shaped region. A second metal layer is deposited over the patterned layer of aperture material. The resulting structure is then lithographically patterned to define an aperture structure comprising aperture material surrounded by metal and having parallel radiation entrance and exit faces orthogonal to the wafer surface.

摘要： A thermally-assisted perpendicular magnetic recording head and system has a head carrier that supports an optical channel for the transmission of radiation to the recording layer, a write pole for directing a magnetic field to the recording layer, and an electrical coil for inducing the magnetic field from the write pole. The optical channel has a radiation exit face with an aperture at the recording-layer-facing surface of the head carrier. The write pole has a pole tip with an end face that is recessed from the recording-layer-facing surface. The write pole tip is tapered down to the end faces. The pole tip taper and the recession of the end face concentrates the write field at the middle of the perpendicular magnetic recording layer where the radiation from the optical channel is incident. The characteristic dimension of the aperture and the spacing between the aperture and the recording layer are both less than the wavelength of the radiation. The radiation source may be a laser diode mounted to the head carrier.

摘要： A thermally-assisted recording (TAR) disk drive uses “shingled” recording and a rectangular waveguide as a “wide-area” heat source. The waveguide generates a generally elliptically-shaped optical spot that heats an area of the recording layer extending across multiple data tracks. The waveguide core has an aspect ratio (cross-track width to along-the track thickness) that achieves the desired size of the heated area while locating the peak optical intensity close to the trailing edge of the write pole tip where writing occurs. The large cross-track width of the waveguide core increases the volume of recording layer heated by the optical spot, which reduces the rate of cooling. This moves the peak temperature point of the heated area closer to the write pole tip and reduces the temperature drop between the peak temperature and the temperature at the trailing edge of the write pole tip where writing occurs.

摘要： A thermally-assisted recording (TAR) slider has an integrated TAR head and an integrated laser diode. The laser diode may be an external-cavity VCSEL that includes a semiconductor substrate with the VCSEL formed on one surface, an external cavity on the opposite surface, and an output third mirror on the output surface of the external cavity. The TAR head is integrated with the slider at the trailing end and includes an optical waveguide having a grating coupler oriented in a plane generally parallel to the slider trailing end, and a near-field transducer (NFT) at the slider air-bearing surface (ABS) and coupled to the waveguide. A carrier is attached to the slider and has a base portion that supports the external-cavity VCSEL so that the linear path of its output laser beam is aligned with and oriented orthogonal to the plane of the grating coupler. The grating coupler receives the laser radiation and turns it 90 degrees into the waveguide, which directs the laser radiation to the NFT at the ABS.

摘要： A thermally-assisted recording (TAR) disk drive uses a “wide-area” heater with “shingled” recording. In shingled recording, the write head pole tip is wider than the read head in the cross-track direction and writes magnetic transitions by making a plurality of consecutive circular paths that partially overlap. The non-overlapped portions of adjacent paths form the data tracks, which are thus narrower than the width of the write pole tip. The data tracks are grouped into annular bands and when data is to be rewritten, all of the data tracks in an annular band are also rewritten. The wide-area heater may be a waveguide with an output end that generates a heated area on the disk recording layer which is wider than the cross-track width of the write pole tip. It has been determined that the use of a wide-area heater with shingled recording does not result in any significant adjacent track erasure (ATE).
摘要翻译：热辅助记录（TAR）磁盘驱动器使用“广域”加热器，“带状”录音。在带状闪烁的记录中，写头磁极尖在交叉磁道方向上比读取头宽，并且通过使多个部分重叠的连续圆形路径写入磁转变。相邻路径的非重叠部分形成数据轨道，因此比写入磁极尖端的宽度窄。数据轨道被分组成环形带，并且当数据被重写时，环形带中的所有数据轨迹也被重写。广域加热器可以是具有输出端的波导，该输出端在盘记录层上产生比写极尖的横越轨道宽度更宽的加热区域。已经确定，使用具有带灰度记录的广域加热器不会导致任何显着的相邻轨道擦除（ATE）。
