Monitoring and adjusting a motor current in a disk data drive to optimize a disk rotation speed

摘要

A method for monitoring and adjusting a motor current in a disk data drive allows to adjust a rotation speed of a disk to be as high as possible in order to increase an overall performance of the disk data drive. It comprisesmeasuring the value of the motor current fed to the motor for an actual value of the disk rotation speed,comparing the value of the motor current with a nominal value of motor current at the actual value of the disk rotation speed,increasing the disk rotation speed to a new actual value of the disk rotation speed if the value of the motor current is substantially equal to the nominal value of motor current.
