Abstract
Data is recorded on a magnetic recording disk with data transducers adjustably positioned relative to respective "data zones," each zone comprising a prescribed number of adjacent data tracks. A family of such transducers may be mounted together as a unitary recording head which is positionable radially over an excursion approximating the width of the (multi-track) data zones. A typical head reciprocation excursion approximates from one dozen to several dozen mils; thus, the heads are aptly mounted on flexure pivots and reciprocated directly by electro-magnetic means which are mechanically isolated from the head array.
