    • Methods of defining servo patterns and data patterns for forming patterned magnetic media are described. For one method, a lithographic process is performed to define a servo pattern in servo regions on a substrate. The lithographic process also defines a first data pattern in data regions of the substrate. The first data pattern is then transferred to (i.e., etched into) the data regions. Self-assembly structures are then formed on the data pattern in the data regions to define a second data pattern. The servo pattern is then transferred to the servo regions and the second data pattern is transferred to the data regions. Thus, the servo pattern is defined through lithographic processes while the data pattern is defined by a combination of lithographic processes and self-assembly.
    • 描述了定义用于形成图案化磁性介质的伺服图案和数据图案的方法。 对于一种方法,执行光刻处理以在衬底上的伺服区域中定义伺服图案。 光刻工艺还定义了衬底的数据区域中的第一数据模式。 然后将第一数据模式转移到(即蚀刻)数据区。 然后在数据区域中的数据模式上形成自组装结构以定义第二数据模式。 然后将伺服模式传送到伺服区域,并将第二数据模式传送到数据区域。 因此,通过光刻工艺定义伺服图案,同时通过光刻工艺和自组装的组合来定义数据图案。

    • A hard disk drive (HDD) has a stack of disks mounted on a rotatable spindle with the disks being movable axially, i.e., in a direction parallel to the axis of rotation of the spindle. A disk separator is located inside the spindle and separates axially-adjacent disks in a pair to create an axial gap. Any pair of axially-adjacent disks can be separated so that different axial gaps are created. A single head-arm assembly with at least one and preferably two read write heads is movable axially so that it can be rotated by the rotary actuator into any one of the axial gaps. The read/write heads can thus access data on the disk surfaces in the axial gaps. When it is desired to have the disk separator create an new axial gap and thus a new pair of disk surfaces to be accessed, the actuator rotates the head-arm assembly away from the outer perimeters of the disks and moves the read/write heads onto a head support structure that supports the read/write heads off the disks.
    • 硬盘驱动器(HDD)具有安装在可旋转主轴上的盘堆,盘可以轴向移动,即在与主轴的旋转轴线平行的方向上移动。 磁盘分离器位于主轴内部并且分离成一对轴向相邻的磁盘以产生轴向间隙。 可以分离任何一对轴向相邻的盘,使得产生不同的轴向间隙。 具有至少一个并且优选两个读写头的单个头臂组件可轴向移动,使得其可以由旋转致动器旋转到任何一个轴向间隙中。 因此,读/写头可以在轴向间隙中访问磁盘表面上的数据。 当希望磁盘分离器产生新的轴向间隙并且因此产生一对新的待访问的盘表面时,致动器将头臂组件旋转远离盘的外周,并将读/写头移动到 一个头部支持结构,支持磁盘上的读/写磁头。

    • 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.
    • 图形媒体磁记录磁盘驱动器使用光学系统来准确地计时写入数据。 磁盘具有图案化成离散的可磁化数据岛之间的同心数据轨道,岛之间具有非磁性空间。 当盘旋转时,辐射源将近场辐射引导到岛和空间,并且辐射检测器接收反射的辐射。 辐射从源通过支撑读写头的含气滑块上的光通道或波导引导。 光通道或波导在滑块的面向盘的表面处具有近场换能器,其中近场辐射离开并且反射辐射返回。 反射的光功率取决于近场换能器耦合到岛还是空间,因此辐射检测器输出信号表示盘旋转时岛的频率和相位。 将写入脉冲控制到写入头的写入时钟响应于辐射检测器输出信号,因此当时间盘旋转时,写时钟信号的频率和相位可以与岛的频率和相位匹配。
