Abstract: A mount for adjusting the position of a photodetector in a fine range is described. The adjustment of the photodetector is carried in one direction or both directions along X and/or Y axis in a condition that the photodetector is fixed on a base plate by fixing the photodetector on the mount of an optical instrument, and is also for fine adjustment of a position of the photodetector by a set screw or a general screw by forming cantilever supporting working points at one or more places of the mount and by installing said set screw at a place opposite to the working points.

Abstract: Correction of the ellipticity of a diode laser beam is achieved by an anamorphic beam expansion prism pair that are separated by an angularly rotationally adjustable mirror. The first prism of the prism pair is rotationally adjustable to various detent positions about a first axis and is translatable to various detent positions along a second axis, while the second prism has a fixed position. The first prism provides some beam expansion and the second prism provides the remainder of the beam expansion. The amount of beam expansion by the first prism is varied by adjustment of its rotation and translation, yet the expanded beam from the first prism exhibits zero positional offset at the location of the rotatable mirror. The mirror is rotated such that the optical axis between the mirror and the second prism is the same for all cases of beam expansion.

Abstract translation: 二极管激光束的椭圆率校正通过由角度可旋转调节的反射镜分开的变形光束扩展棱镜对实现。 棱镜对的第一棱镜可旋转地调节到关于第一轴线的各种定位位置，并且可平移到沿着第二轴线的各种定位位置，而第二棱镜具有固定位置。 第一棱镜提供一些光束扩展，第二棱镜提供光束扩展的剩余部分。 由第一棱镜的光束膨胀量通过其旋转和平移的调节而改变，但是来自第一棱镜的扩展光束在可旋转镜的位置处表现出零位置偏移。 反射镜旋转，使得反射镜和第二棱镜之间的光轴对于所有的光束膨胀的情况都是相同的。

Abstract: A linear actuator for controlling access to a track element belonging to a plurality of adjacent track elements arranged in a reference surface of an optical disk rotatable about a spindle. The linear actuator includes an objective lens for projecting a light spot for interaction with a selected one of the track elements. A first moving mechanism is provided for supporting the objective lens for movement along a first direction substantially perpendicular to the reference surface for controlling the focusing of the light spot. A second moving mechanism in the linear actuator supports the objective lens for movement along a second direction substantially parallel to the reference surface and generally transverse to the track elements for controlling the access thereto. The second moving mechanism includes a pair of spaced apart, parallel rods which extend generally transverse to the track elements. The rods have a round cross-section and are made of a ferromagnetic material. The objective lens is supported by a carriage which is engaged with the rods for movement along the same. A pair of round actuator coils are connected to the carriage and surround corresponding ones of the rods for linear movement along the same. Each rod is partially surrounded by a generally C-shaped radially polarized permanent magnet so as not to obstruct movement of the carriage along the rod. A return flux path is provided adjacent each of the magnets.

Abstract: A servo track writer for a head disk assembly and a method of making the head disk assembly using the servo track writer are disclosed. The head disk assembly includes an enclosure having an opening and a base and an actuator arm coupled to the base and having a servo writer positioning arm facing surface. The servo track writer includes a platform for supporting the head disk assembly. The platform includes a base portion, a column extending substantially perpendicular to the base portion, and an elongated servo writer positioning arm for protruding through the opening and supported by the column. The positioning arm includes a main body, a tip having an actuator arm facing surface for abutting the positioning arm facing surface, and a vibration damper positioned between the main body and the tip. The vibration damper damps vibrations induced in the actuator arm by dissipating energy transferred between the platform and the actuator arm.

Abstract: A head gimbal assembly includes a slider and novel gimbal that may reduce crown sensitivity to temperature without substantially sacrificing the ability of a bond between the gimbal tongue and slider to resist applied forces and torques. The gimbal has a tongue that includes at least one weakening region. The weakening region extends more in a direction perpendicular to the length of the slider than it does in a direction parallel to the length of the slider. A bonding surface of the slider is attached to the tongue in a first bonding region that extends closer to a leading end of the slider than the weakening region does, and in a second bonding region that extends closer to a trailing end of the slider than the weakening region does. The gimbal can be used in a head gimbal assembly of a magnetic hard disk drive or other information storage device.
