Electronic system with current conservation mechanism and method of operation thereof |
| 摘要 |
An apparatus includes: a media motor; a media mounted on the media motor; a head, over the media, the motion of the head controlled by a head actuation motor; a motor driver, coupled to the media motor, configured to adjust a media speed; and control circuitry configured to: coast the media motor in preparation for accelerating the head, and activate the head actuation motor including accelerating the head in a first direction for repositioning the head over the media. |

1. An apparatus comprising:
a media motor; a media mounted on the media motor; a head, over the media, the motion of the head being controlled by a head actuation motor; a motor driver, coupled to the media motor, configured to adjust a media speed; and control circuitry configured to:
coast the media motor in preparation for accelerating the head,activate the head actuation motor including accelerating the head in a first direction for repositioning the head over the media,increase a speed of the media motor by a fixed percentage in a motor pitch region after accelerating the head, andcoast the media motor in preparation for decelerating the head. |
