摘要： A transducer is moved in a seek operation from an initial track to a target track on a disk based on a current command. The current command is regulated based on a location of the transducer and a location of an addressed data block on the disk. The current command may be regulated so that the transducer settles on the target track a predetermined time before the addressed data block reaches the transducer.

摘要： Bias force changes in a disk drive, including transient bias changes, are predicted and/or estimated. Bias compensation or change in bias compensation is calculated based on drive operating parameters such as seek length. Calculation can correspond to a modeled relationship of bias forces to seek length. Preferably, bias compensation calculation is adaptive and calculation parameters can be updated during normal read/write use of the disk drive.

摘要： Methods of controlling seeking of a transducer that is adjacent to a rotatable disk in a disk drive include determining an expected seek time associated with moving the transducer from an initial track to a target track on the disk. An expected rotational latency time is determined which is associated with rotating the disk to move an addressed data block on the target track adjacent to the transducer after the transducer would be expected to arrive at the target track. A scaled velocity limit is determined which is based on the expected seek time and the expected rotational latency time. While seeking the transducer from the initial track to the target track, the radial velocity of the transducer relative to the disk is regulated in response to the scaled velocity limit. Related apparatus for controlling seeking of a transducer are also described.

摘要： Methods of controlling a transducer that is adjacent to a rotatable data storage disk in a disk drive are disclosed, the disk drive having an actuator configured to position the transducer, a rotational acceleration sensor configured to generate a rotational acceleration signal, a position error sensor configured to generate a position error signal, and a controller configured to control the actuator to move the transducer to a target track during a seek operation. The methods include dynamically adjusting a gain factor in response to the position error signal and the acceleration signal during a settle period following the seek operation, multiplying the rotational acceleration signal by the gain factor to generate an adjusted rotational acceleration signal, and adding the adjusted acceleration signal to the position error signal to generate an adjusted position error signal, and moving the transducer in response to the adjusted position error signal.

摘要： A transducer is controlled during seeking based on an acceleration-phase state error. While seeking, the transducer is moved from an initial track to a target track on the disk based on a current command. At least one transducer state relative to the disk is estimated while seeking. At least one transducer state relative to the disk is measured while seeking. An acceleration-phase state error is determined that is indicative of an error between the estimated at least one transducer state and the measured at least one transducer state as the transducer is accelerated toward the target track during the seeking. The current command is generated based on the acceleration-phase state error.
