摘要： A patterned-media magnetic recording disk drive uses an optical system for clocking the write data and a patterned-media disk that has discrete magnetizable data islands with nonmagnetic spaces between the islands, wherein the nonmagnetic spaces contain optical contrast material. The optical contrast material may be optically absorptive material, fluorescent material, or a metal layer that generates surface plasmons when excited by radiation of a specific wavelength. Radiation from a primary radiation source is directed to a near-field transducer maintained near the disk surface and a radiation detector detects radiation reflected back from the transducer. If the disk has fluorescent material or a metal layer in the nonmagnetic spaces, then a secondary radiation source irradiates the fluorescent material or metal layer with radiation of a specific wavelength to cause the fluorescent material to emit radiation or the metal layer to generate surface plasmons. As the disk rotates, reflected optical power from the transducer varies depending on whether an island or space is under the transducer. The output signal from the radiation detector output controls the write clock.
摘要翻译：图案介质磁记录磁盘驱动器使用光学系统对写入数据进行计时，并且图案化介质盘具有在岛之间具有非磁性空间的离散可磁化数据岛，其中非磁性空间包含光学对比材料。光学对比材料可以是光吸收材料，荧光材料或当通过特定波长的辐射激发时产生表面等离子体激元的金属层。来自主辐射源的辐射被引导到保持在盘表面附近的近场换能器，并且辐射检测器检测从换能器反射的辐射。如果磁盘在非磁性空间中具有荧光材料或金属层，则辅助辐射源用特定波长的辐射照射荧光材料或金属层，以使荧光材料发射辐射或金属层以产生表面等离子体激元。当盘旋转时，来自换能器的反射光功率取决于岛或空间是否在换能器之下。来自辐射检测器输出的输出信号控制写入时钟。

摘要： A method using directed self-assembly of BCPs enables the making of a master disk for nanoimprinting magnetic recording disks that have patterned data islands and patterned binary encoded nondata marks. The method uses guided self-assembly of a BCP to form patterns of sets of radial lines and circumferential gaps of one of the BCP components, which can be used as an etch mask to make the master disk. The sets of radial lines and circumferential gaps can be patterned so as to encode binary numbers. The pattern is replicated as binary encoded nondata marks into the nanoimprinted disks, with the marks functioning as binary numbers for data sector numbers and/or servo sector numbers. If the disks also use a chevron servo pattern, the binary numbers can function to identify groups of tracks associated with the chevron servo pattern.

摘要： A patterned perpendicular magnetic recording disk with discrete data islands of recording layer (RL) material includes a substrate, a patterned exchange bridge layer of magnetic material between the substrate and the islands, and an optional exchange-coupling control layer (CCL) between the exchange bridge layer and the islands. The exchange bridge layer has patterned pedestals below the islands. The exchange bridge layer controls exchange interactions between the RLs in adjacent islands to compensate the dipolar fields between islands, and the pedestals concentrate the flux from the write head. The disk may include a soft underlayer (SUL) of soft magnetically permeable material on the substrate and a nonmagnetic exchange break layer (EBL) on the SUL between the SUL and the exchange bridge layer. In a thermally-assisted recording (TAR) disk a heat sink layer may be located below the exchange bridge layer and the SUL may be optional.

摘要： A method for making a master disk for nanoimprinting patterned-media magnetic recording disks has patterns for both the data islands and the nondata regions. The method uses guided self-assembly of a block copolymer (BCP) to form patterns of generally radial lines and/or generally concentric rings as well as patterns of gap regions of one of the BCP components. The pattern of lines and/or rings have the BCP components aligned as lamellae perpendicular to the substrate, while the pattern of gap regions has the BCP components aligned as lamellae parallel to the substrate. One of the BCP components is removed, leaving the other BCP component as an etch mask to fabricate either the final master disk or two separate molds that are then used to fabricate the master disk.

摘要： A patterned perpendicular magnetic recording disk has a pre-patterned disk substrate with pillars and trenches arranged in data regions and servo regions. In the data regions, the height of the data pillars is equal to or greater than the spacing between the data pillars, while in the servo regions the height of the servo pillars is less than the spacing between the servo pillars. A magnetic recording material with perpendicular magnetic anisotropy is deposited over the entire disk substrate, which results in magnetic material on the tops of the data pillars and servo pillars and in the servo trenches. The material in the data trenches is either nonmagnetic or discontinuous. After the application of a high DC magnetic field in one perpendicular direction and a low DC magnetic field in the opposite direction, the resulting disk has patterned servo sectors with servo pillars all magnetized in the same perpendicular direction and servo trenches magnetized in the opposite perpendicular direction.

摘要： A patterned-media magnetic recording disk drive uses an optical system for clocking the write data and a patterned-media disk that has discrete magnetizable data islands with nonmagnetic spaces between the islands, wherein the nonmagnetic spaces contain optical contrast material. The optical contrast material may be optically absorptive material, fluorescent material, or a metal layer that generates surface plasmons when excited by radiation of a specific wavelength. Radiation from a primary radiation source is directed to a near-field transducer maintained near the disk surface and a radiation detector detects radiation reflected back from the transducer. If the disk has fluorescent material or a metal layer in the nonmagnetic spaces, then a secondary radiation source irradiates the fluorescent material or metal layer with radiation of a specific wavelength to cause the fluorescent material to emit radiation or the metal layer to generate surface plasmons. As the disk rotates, reflected optical power from the transducer varies depending on whether an island or space is under the transducer. The output signal from the radiation detector output controls the write clock.
