FLEX CIRCUIT VIBRATION SENSOR |
摘要 |
A method and apparatus for sensing vibration in a flex circuit located between a rotary actuator and electronics within a disk drive. Specifically, the apparatus contains a strain gauge attached to or imbedded within the flex circuit. The resistivity of the strain gauge varies in response to vibrations on the cable. This resistance variation can be transformed into electrical signals that are used by a servo system to move the actuator assembly in compensatory motion that effectively cancels any off-track motion caused by the vibrations. |
