Mechanical damper for disk drives having band drive actuators

Image Number 3 for United States Patent #4598328.

To damp a stepper motor powered band drive for a disk drive, there is a relatively inexpensive, but efficient mechanical damper comprising a predetermined inertial mass which is concentrically coupled to the capstan of the band drive by an energy absorbing elastomer. The mass, its geometry, and the energy absorbing characteristics of the elastomer are selected to apply a dynamic force to the stepper motor which opposes and counteracts any unwanted oscillation of the stepper motor as the read/write head of the disk drive arrives at a selected data track. This damper is relatively free of potential contaminants and is, therefore, particularly attractive for Winchester disk drives.
