Abstract
A method and apparatus for reducing seek acoustics in a disk drive using a variable-bandwidth low-pass filter is provided. The variable-bandwidth low-pass filter is used to adaptively shape a control signal supplied to a VCM for moving a head relative to a disk surface during a seek operation. The bandwidth of the variable-bandwidth low-pass filter is dependent upon head position relative to a target track.
