ABSTRACT:
An improved actuator support structure for supporting rotary actuator coils in a disc drive system. The support structure includes a support which extends from a central portion to the actuator coil so that when the coil is excited, the coil will remain in tension. The invention increases all natural frequencies of the actuator coil so that servo stability is enhanced. In a preferred embodiment, the support structure fits into a magnetic pole piece such that the actuator coil occupies a gap space between a front leg and a back leg of the magnetic pole piece.
