Abstract
The present disclosure includes systems and techniques relating to control of storage device, such as disk drives. A described technique includes controlling a motor to actuate a head within a storage device, the motor being associated with first and second states of electric current, where a duration of the first state is longer than a duration of the second state. Controlling the motor can include using both a first mode and a second mode to control current to the motor. The technique further includes detecting an instance of the first state, and initiating, when the instance of the first state is detected, a switch from the first mode to the second mode to control the motor. The switch can be based on a condition of operation with respect to the storage device. A start-up time of the second mode is shorter than the duration of the first state.
