摘要：

A new milli-scale piggyback actuator for magnetic disk drives with a high track density was developed. The movable part of this actuator is comprised of a head suspension assembly supported by a 'flexural' cross-shaped spring, driven in the rotary direction by electromagnetic force. The advantages are that the actuator moves over a long distance with small power and can be easily manufactured. Our dual-stage actuator system using the flexural milli-actuator can realize 25 kTPI.
