Abstract :
For moving coil actuator (voice coil motor) implemented in disk drives, the access time is computed for different types of steels. For each type of steel used in the actuator a set of optimized dimensions are found, given the mechanical, electrical, and material constraints. A flow chart of the optimization procedure is presented and commented upon. A discussion of the practicality of the results is included.<>
