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.

摘要： The present invention relates to a write control method of a hard disk drive, a hard disk drive adapting the method, and a recording medium storing a program for executing the method. The write control method of a hard disk drive having a disk where servo bursts are written radially comprises: generating a primary position error signals (PESs) with respect to a target offtrack based on a difference between servo burst signals read from two adjacent servo bursts; generating a secondary PES with respect to the target offtrack based on a sum of the primary PESs or a difference there between; determining whether both the primary PESs and the secondary PES are within a predetermined write bump limit; and performing a write operation at the target offtrack if both the primary PESs and the secondary PES are within the predetermined write bump limit, otherwise prohibiting the write operation.
