Abstract
A disc drive device includes a base plate having an upper surface, a voice coil motor operably attached to the upper surface of the base plate, and a damper pad positioned on the upper surface of the base plate between the base plate and the voice coil motor such that vibrations occurring in the base plate and/or the voice coil motor are effectively damped. In this manner, vibrationally induced noise in a disc drive servo system and vibrationally induced acoustical emissions from the disc drive device are reduced.
Claims21
A disc drive comprising:
- a base plate having an upper surface;
- a voice coil motor separate from the base plate operably attached to the upper surface of the base plate;
- and
- a damper pad positioned on the upper surface of the base plate between the base plate and the voice coil motor for damping vibrations occurring in the base plate and the voice coil motor.
A disc drive comprising:
- a base plate having an upper surface;
- a voice coil motor separate from the base plate operably attached to the upper surface of the base plate, the voice coil motor having a lower magnetic plate spaced from the upper surface of the base plate;
- a damper pad positioned on the upper surface of the base plate between the base plate and the lower magnetic plate for damping vibrations occurring in the base plate and the lower magnet plate.
A disc drive damping system comprising:
- a disc drive having a base plate and a voice coil motor separate from the base plate connected to the base plate;
- and
- a damping means positioned between the voice coil motor and the base plate for damping vibrations in the disc drive.
