摘要： A system includes a servo writing module, a position measuring module, and a compensation module. The servo writing module writes a first set of servo wedges on a magnetic medium of a hard disk drive (HDD) using a head of the HDD. The position measuring module measures a position of the head when the head writes the first set of servo wedges and generates a first measured head position. The compensation module generates first compensation data based on the first measured head position to compensate a repeatable error component of the first measured head position. The servo writing module writes the first compensation data on the magnetic medium when writing the first set of servo wedges and writes second compensation data generated based on the first set and the first compensation data read from the magnetic medium when writing a second set of servo wedges on the magnetic medium.

摘要： Systems, methods and computer program products for removing speed adjustment errors attributed by pole asymmetry are described. In some implementations, the spindle motor speed can be down sampled. Down sampling the spindle motor speed can include determining the spindle motor speed every two (or multiple of two) electrical cycles. Determining the spindle motor speed every two electrical cycles can lead to an accurate determination of the actual spindle motor speed, as the timing and position differences between two adjacent poles can be equalized (e.g., timing and position errors associated with the second pole can be used to cancel out the timing and position characteristics errors with the first pole).

摘要： A system including an error signal generating module to generate an error signal based on (i) back electromotive force sensed from a motor and (ii) a predetermined speed of the motor. The error signal includes noise due to mismatched poles of the motor. A noise elimination module eliminates components of the noise having frequencies N times a frequency of rotation of the motor from the error signal and generates a corrected error signal, where N is an integer greater than or equal to zero. A control module generates a first control signal based on components of the corrected error signal, generates a second control signal based on components of the error signal, and rotates the motor at the predetermined speed based on (i) the first control signal and (ii) the second control signal. The components of the corrected error signal have higher frequencies than the components of the error signal.
