Method in order to control the motor electric power of disk drive and the disk drive which possess the motor electric power regulator and the motor electric power regulator for disk drive

摘要

This invention regards the motor electric power regulator for disk drive. Furthermore, this invention regards the method in order to control the motor electric power of disk drive and the disk drive which possess the motor electric power regulator. The portable computer or like the DVD player, the portable kind of audio like the laptop computer/the video system or other portable device, usually, operates by battery electric power. The important factor which decides battery life is disk drive. In order to convert battery life maximally, it is necessary to improve the efficiency of disk drive. This invention, being disk drive, especially, being the motor electric power regulator for disk drive of the formal device, at least two working conditions of disk drive, namely, continuing the motor of disk drive, with the 1st working condition which it operates and the description above spins raises the tar when starting each data handling and the 2nd working condition which it spins knocks down the motor possesses the expedient which stipulates that end time, the motor electric power regulator for disk drive is offered. That motor electric power regulator, when no data request the long time interval is decided from dying specified period, has the expedient which from the aforementioned 1st working condition moves the aforementioned disk drive to the aforementioned 2nd working condition. Furthermore, that motor electric power regulator, when being decided, that predetermined number of the time interval during continual data request, those everything or each is short from the aforementioned specified period, has the expedient which from the aforementioned 2nd working condition moves the aforementioned disk drive to the aforementioned 1st working condition.
