POWER STATE CHANGE IN DISK DRIVE BASED ON DISK ACCESS HISTORY |
| 摘要 |
A data storage device that includes a magnetic storage device selects one or more power states of the magnetic storage device based on a time interval since a most recent time data has been read from or written to the magnetic storage device. The power state of the magnetic storage device can be changed from a higher power consumption state to a lower power consumption state when the time interval exceeds a predetermined value. The power consumption state may be changed from an active servo state to an intermediate power consumption state, a park state, and/or a standby state, depending on the time elapsed since the most recent time data has been read from or written to the magnetic storage device. |

1. A method of power management in a data storage device that includes a magnetic storage device, the method comprising:
measuring a time interval since a most recent time data has been read from or written to the magnetic storage device; and in response to the time interval exceeding a predetermined value, changing a current power consumption state of the magnetic storage device to a lower power consumption state. |
