    摘要: Methods relating to compensating a pre-defined seek profile for use in a data storage device, such as a disc drive, to manage the internal temperature of the device are disclosed. One embodiment disclosed is related to determining a seek profile compensation value that can be used to compensate the pre-defined seek profile for temperature. Another embodiment is a method of using a seek profile compensation value during device operation to maintain the data storage device operating temperature below an operating temperature threshold. Yet another embodiment of the present invention may be thought of as a controller for a data storage device. The controller comprises a microprocessor having a pre-determined seek profile and a means for compensating the pre-determined seek profile based on a current operating temperature.

    摘要: Method and apparatus for compensating variations in motor torque in a control system that employs a motor to accelerate a control object, such as a data transducing head in a data storage device. During acceleration of the control object, a plurality of distances successively traveled by the control object are measured, and the measured distances are combined to compensate for said variations in motor torque. Preferably, a constant control input is applied to accelerate the control object at a constant rate of acceleration less than a maximum rate of acceleration that can be obtained by the motor. A coarse adjustment routine is preferably applied to arrive at a first compensation value that compensates for said variations at a first resolution, after which a fine adjustment routine is performed using the first compensation value to arrive at the final compensation value at a second resolution greater than the first resolution.
