Abstract
The present invention divides the recording head into multiple sections, each section accessing a subset of the total number of channels arranged such that one section reads and writes only a subset of the data channels. The sections may be either independently actuated for both coarse (data band) and fine (track-following) positioning, or linked by a common actuator for data band positioning with independent fine position actuators for fine track following.
