Disc drive component level shock tester
First Claim
1. A shock test apparatus for evaluating the shock performance of individual disc drive components, the apparatus comprising:
- a base portion;
a top cover detachably secured to the base portion to define an interior volume;
first and second disc drive components detachably secured within the interior volume of the apparatus so that the first disc drive component contacts the second disc drive component in the absence of a shock event;
a shock pulse generator extending into the interior volume of the apparatus, the shock pulse generator having an actuator that moves vertically in relation to the generator, the actuator imparting a shock pulse to the first disc drive component to create a dynamic interaction between the first and second disc drive components.

Abstract
A shock test apparatus for evaluating the shock performance of individual disc drive components includes a base portion and a top cover connected to the base portion to define an interior volume. First and second disc drive components are secured within the interior volume of the apparatus to engage one another in the absence of a shock event. A shock pulse generator includes an actuator for imparting a shock pulse to one of the disc drive components. A second shock pulse generator can be used to impart a shock pulse to the second disc drive component. Means are included for measuring the shock imparted to the disc drive components and for measuring the interaction between the first and second disc drive components during the shock event.

15. A system for evaluating the shock performance of individual disc drive components, the system comprising:
-
an enclosure having a base portion and a top cover detachably secured together to define an interior volume of the enclosure, the enclosure securing first and second disc drive components within the interior volume so that the first disc drive component contacts the second disc drive component in the absence of a shock event;
a shock pulse generator having an actuator extending into the interior volume of the enclosure, the actuator moving vertically to impart a shock pulse to the first disc drive component to create a dynamic interaction between the first and second disc drive components;
means for measuring the shock pulse imparted to the first disc drive component; and
means for measuring the dynamic interaction between the first and second disc drive components.

25. A system for evaluating the shock performance of individual disc drive components, the system comprising:
-
a first disc drive component engaging a second disc drive component in the absence of a shock event; and
means for imparting a shock to the first disc drive component to observe the shock performance of the first and second disc drive components without assembling the first and second disc drive components in a disc drive.
