Abstract:
1. A method for dispersing energy from an impact between a head stack assembly and a crash stop within a HDD, the method comprising: receiving a contact event between the crash stop and the head stack assembly; rotating the crash stop so that a first protrusion of the crash stop comes into contact with a portion of the HDD, the first protrusion undergoing a deformation during contact such that some of the energy from the impact between the crash stop and the head stack assembly is absorbed by said first protrusion; utilizing a repelling force of the first protrusion to rotate the crash stop in an opposite direction thereby dispersing the energy absorbed by said first protrusion; rotating the crash stop so that a second protrusion of the crash stop comes into contact with a portion of the HDD, the second protrusion undergoing a deformation during contact such that some of the energy from the impact between the crash stop and the head stack assembly is absorbed by said second protrusion; and utilizing a repelling force of the second protrusion to rotate the crash stop in the opposite direction and disperse the energy absorbed by said second protrusion.
