Abstract

Claims (11)

1. A damper for a data storage device comprising:

a viscoelastic material having a top and bottom, with the bottom attached to a surface of the data storage device to absorb and reduce external shock and vibration; and

a solid constraint material attached to the top of the viscoelastic material by an adhesive, as a cover for the viscoelastic material, with an edge offset extending toward the surface of the data storage device, covering the sides of the viscoelastic material, the edge offset forming a pocket between an inside wall of the edge offset and a side of the viscoelastic material for containing the adhesive.

2. The damper of claim 1 , wherein the viscoelastic material is a viscoelastic polymer with a double sided pressure sensitive adhesive on the top and bottom.

3. The damper of claim 1 , wherein the constraint material is selected from a group consisting of aluminum, stainless steel, nickel-plated steel, zinc, copper, nickel, ceramic, mylar and elastomeric material.

4. The damper of claim 1 , wherein the constraint material also has a flanged edge extending from the edge offset parallel to the surface of the data storage device.

5. The damper of claim 1 wherein the viscoelastic material thickness ranges from as low as about 0.0002″ to as much as about 0.005″.

6. The damper of claim 1 wherein the constraint material thickness ranges from as low as about 0.0002″ to as much as about 0.005″.

7. The damper of claim 1 wherein the length of the damper ranges from about 0.200″ to as much as about 2.000″.

8. The damper of claim 1 wherein the width of the damper ranges from about 0.100″ to as much as about 1.000″.

9. The damper of claim 1 comprising at least one additional layer of viscoelastic material.
