Zusammenfassung:A method and system for buffering power for rotating media devices. A power management circuit includes a power augmentation circuit and a power storage device. The power augmentation circuit is arranged to sense when the storage device motor is accelerating and to supply additional power to the storage device motor in response thereto. The power storage device is arranged to store the additional power. The power storage device may be trickle charged from the system power supply and may also be charged as power is recaptured from the storage device motor as it decelerates.
