- Abstract
- A design strategy of the rotary moving coil actuator is presented for a computer hard disk drive. This paper puts a focus on a coil diameter of the rotary moving coil actuator for the given mechanical properties and magnetic characteristics. To achieve the criteria for the coil diameter, the seek rime and power consumption are expressed in terms of the coil conductor diameter. This study shows that the seek time decreases but the power consumption increases as the coil conductor diameter increases. Therefore, the coil design makes a compromise over the seek time and power consumption. An example of the coil diameter design is given to obtain the appropriate coil diameter satisfying the specifications on the seek rime and power consumption.
