Abstract:
1. A storage device comprising: a storage medium; a motor to spin the storage medium; a data reading device to read data from the storage medium; a usage pattern monitor adapted to generate and store usage pattern maps specifying relations between a plurality of data locations on the storage medium and (1) at least one of frequency of read operations performed at the data locations and frequency of write operations performed at the data locations and (2) density of data at the data locations, and to generate a usage pattern signal based on the usage pattern maps; and the control circuit further responsive to the usage pattern signal to: (a) change a level of power delivered to the motor to change a speed of rotation of the storage medium from a first speed to a second speed, and (b) to synchronize operation of the data reading device to the second speed of rotation of the storage medium.
