Abstract :
The dynamic characteristics of head/disk interface and lift-tab/ramp interface in hard disk drives subject to an external shock were modeled. The displacement responses to the half sinusoidal impulse with different duration and acceleration amplitude were simulated. The dynamic behavior of dual sliders at the interface was analyzed based on the shock response of sliders and the contact at the head/disk interface and the contact between the components of suspension assembly. The results can be beneficial to further application of load/unload technology.
