Abstract
A fixed disc drive type of rotating disc memory storage device includes an annular elastomeric pad that is engaged between the actuator base plate and a bowl-shaped casing. The base plate has a circular platform portion with the boss for the spindle shaft for the discs being formed at its center. The annular pad forms an air-tight seal at the edge of a circular opening in the lower casing to prevent dust from entering the housing. The annular pad is engaged against the entire side marginal area of the base plate so that it dampens resonant vibrations in the base plate thus providing stable servo response within the range of said resonant vibration range.
