    • Systems and methods for flexure based shock and vibration sensor for head suspensions in hard disk drives. Specifically, this invention deals with operational shock and vibration management within a hard disk drive. In one implementation, the assembly includes a circuit embedded optical waveguide sensor that includes a flexible electrical circuit board with a configuration of either a single or multi layers of conductor traces, a thin flexure gimbal for carrying and flying a HDD slider, a consecutive sensing layer constructed by an optical core and by clad construction with a configuration of either a single core array or a plural core array, an optical loop formed by light input and an output core, optical grating disposed on the consecutive sensing layer forming an optical grating waveguide sensor, a light emitter for injecting light into the optical core, and a receiver receiving the output light from the optical core.

    • A disk drive apparatus. The apparatus has a first drive device and a support member coupled to the first drive device. The support member has a tongue portion and a gimbal portion. The tongue portion is coupled the gimbal portion. A fixed drive device is formed within a first portion of the tongue portion. A movable drive device is operably coupled to the fixed drive device and formed within a second portion of the tongue portion. A read/write head is coupled to the movable drive device. A voltage source is coupled between the fixed drive device and the movable drive device to cause movement of the read/write head by forming an interaction between the fixed drive device and the movable drive device.
    • 磁盘驱动装置。 该装置具有联接到第一驱动装置的第一驱动装置和支撑构件。 支撑构件具有舌部和万向节部。 舌部连接在万向节部分上。 固定驱动装置形成在舌部的第一部分内。 可移动驱动装置可操作地联接到固定驱动装置并形成在舌部的第二部分内。 读/写头耦合到可移动驱动装置。 电压源耦合在固定驱动装置和可移动驱动装置之间,以通过形成固定驱动装置和可移动驱动装置之间的相互作用来引起读/写头的移动。
