    • A dual actuator arm assembly system that uses two pairs of actuator-carriage arms (13-14) that linearly move over a stationary micro-rail (15-16) independently. The geometric shape of the two pairs of actuator carriage arms (13-14) conform to the arcs of the data tracks (22, 22a, 22b, 23, 23a) at an acute angle. System enables micro­- actuation that is integrated to actuator arm (13-14) and is a function of its geometry. Uninterrupted data stream and sector coverage and thus parallel data transfer scheme is made possible. Each actuator (13-14) move only within a limited range (17, 17a, 18, 18a) of disk area, thus precision is increased, vibration is minimized and external transfer rate is speeded up and overall access time is shortened. Instant access to two quarters (20, 21) of the disk with two pairs of actuators (13-14) and to park these without landing the heads (26, 26a) -by positioning and constant fly height during idle mode, or when system is turned off, are introduced as what are new in the art.
    • 双致动器臂组件系统,其使用两对致动器 - 托架臂(13-14),其独立地在固定微轨(15-16)上线性移动。 两对致动器支架臂(13-14)的几何形状以锐角与数据轨道(22,22a,22b,23,2aa)的弧线一致。 系统实现了与致动器臂(13-14)集成的微动作,并且是其几何形状的函数。 不间断的数据流和扇区覆盖以及并行数据传输方案成为可能。 每个致动器(13-14)仅在盘区域的有限范围(17,17a,18,18a)内移动,因此精度提高,振动最小化,外部传送速度加快,总体访问时间缩短。 通过两对执行器(13-14)即时访问磁盘的两个季度(20,21),并且在空闲模式下通过定位和恒定飞行高度来停放这些驱动器(26,26a),或者当系统 被关闭,被介绍为本领域的新​​技术。

    • An apparatus for producing a small spot of optical energy comprises a planar waveguide shaped to direct a linearly polarized electromagnetic wave to a focal point within the waveguide, and a metallic pin positioned at the focal point whereby the linearly polarized electromagnetic wave creates surface plasmons on a surface of the pin. The apparatus can further comprise means for phase shifting a portion of the linearly polarized electromagnetic wave. Recording heads comprising a magnetic write pole, a planar waveguide positioned adjacent to the magnetic write pole, the planar waveguide being shaped to direct a linearly polarized electromagnetic wave to a focal point within the waveguide, and a metallic pin positioned at the focal point whereby the linearly polarized electromagnetic wave creates surface plasmons on a surface of the pin, and disc drives that use such recording heads are also disclosed.
