摘要： A method for improving disk drive performance by reducing the overhead associated with the command processing code requesting a seek. As multiple commands are queued up in a command queue, a next command is identified and immediately stored in a servo position queue, as soon as the next command location is determined. Therefore, as the drive electronics are prepared for read and write operations, the servo system initiates the actuator to move the read/write head to the next command location. By the time the read/write head arrives at the next command location, the drive electronics are ready for the read/write operation. As a subsequent command is determined, its location is again entered into the position queue, overwriting the previous command location.
