摘要： An adaptive spindle motor startup method includes applying an internal driving voltage to a disk drive, sensing an internal temperature of the disk drive, and controlling the startup of a spindle motor by adjusting a startup factor related to a startup current applied to the spindle motor corresponding to the sensed temperature. Thus, the delay of time to reach a target rotation rate is prevented in the spindle motor in an extreme environment, for example at temperatures lower or higher than 25° C. The overall startup time is efficiently optimized through the improvement of the startup method of the spindle motor.
