Abstract: A dynamic absorber device for absorbing undesirable vibrations and resonances in dynamic machines, such as disk drives, is formed with a viscoelastic link element, an absorber base and an absorber mass. The link element is disposed between the absorber base and the absorber mass to absorb vibratory forces, and to minimize the effects of bending and deformation. The absorber device is assembled to disk drive components, such as the base casting or carriage, to effectively reduce vibrations, undesirable resonances and noise.
Abstract: In the carriage assembly of a disk drive, thermally compensating elements are positioned between the support structure for the carriage and a fixed guide plate which is associated with an outrigger bearing of the carriage. Compensation is achieved for expansion of the carriage base and displacement of the fixed guide plate and the outrigger bearing which results from thermal change, thereby precluding roll of the carriage.
