Drop test of Seagate one inch micro hard disk drives : high speed camera

In this project, a high speed camera is used to capture the video clips of the deflection of a Seagate one-inch micro hard disk drive upon a free drop of 1-inch in the first phase and proceeding to a rotary drop of 30 degrees, 50 degrees and 80 degrees. The video clips are analysed and measurements...
