Abstract:
A disk drive for reading data from a data storage disk, comprising:a retaining frame; a vibration absorber; a first plurality of vibration transfer-dampers coupled to said retaining frame and to said vibration absorber for transferring and damping vibrations, rigidity of said first plurality of vibration transfer-dampers being lower than a predetermined rigidity; a center base, for supporting a motor drive and the data storage disk; a second plurality of vibration transfer-dampers, coupled to said center base and to said vibration absorber, for damping and transferring vibrations of said center base to said vibration absorber, rigidity of said second plurality of vibration transfer-dampers being higher than the predetermined rigidity; wherein vibration of said center base due to rotation of the data storage disk, the rotation being driven by said motor drive, is transferred to said vibration absorber, thereby reducing vibration on said center base and said retaining frame.
