    • 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.
    • 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。

    • A patterned-media magnetic recording disk drive uses an optical system for accurately clocking the write data. The disk has concentric data tracks patterned into discrete magnetizable data islands with nonmagnetic spaces between the islands. As the disk rotates, a radiation source directs near-field radiation to the islands and spaces, and a radiation detector receives reflected radiation. The radiation is directed from the source through an optical channel or waveguide on the air-bearing slider that supports the read and write heads. The optical channel or waveguide has a near-field transducer at the disk-facing surface of the slider where the near-field radiation exits and reflected radiation returns. The reflected optical power varies depending on whether the near-field transducer couples to an island or a space, so the radiation detector output signal represents the frequency and phase of the islands as the disk rotates. The write clock that controls write pulses to the write head is responsive to the radiation detector output signal, so the frequency and phase of the write clock signal can be matched to the frequency and phase of the islands as the disk rotates.
