Abstract:
A computer program product for positioning an actuator, according to one embodiment, includes a computer readable storage medium having program instructions embodied therewith. The computer readable storage medium is not a transitory signal per se. The program instructions are executable by a processing circuit to cause the processing circuit to perform a method that includes generating or receiving, by the processing circuit, a first value representative of a lateral position of a tape, and using, by the processing circuit, the first value to adjust a position of a coarse actuator for moving a magnetic head in response to determining that the first value is in a first range relative to a first threshold. An integrator value is used by the processing circuit to adjust the position of the coarse actuator in response to determining that the first value is in a second range relative to the first threshold.
