Abstract:
1. A method of operating a storage device which is coupled to an information processing system, the method comprising: monitoring one or more operational characteristics of the information processing system; predicting a device access requirement dependent at least in part upon the one or more monitored operational characteristics of the information processing system; and controlling a controllable characteristic of the storage device in a manner dependent at least in part on an operational characteristic of the information processing system, wherein the controlling includes controlling at least one controllable characteristic of the storage device in a manner dependent at least in part on the predicted device access requirement, wherein the controllable characteristic is controllable to any one of a plurality of operational modes that includes at least one intermediate operational mode, wherein the controlling the controllable characteristics includes changing a clock signal frequency of the storage device, changing a power level of the storage device, changing a relative speed between a movable computer readable medium and a data transfer element of the storage device, changing a seek speed of a data read/write head responsive to a change in the operational characteristic, changing a detection threshold of a data read/write head of the storage device responsive to a change in the operational characteristic, changing data transfer timing of a read/write head of the storage device responsive to a change in the operational characteristic, or changing circuit filter values of a data detection circuit of the storage device responsive to a change in the operational characteristic.
