Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 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.
