Magnetic head and system for controlling the position of a magnetic head
WO 1996030897 A3
Abstract
Write head, particularly a buried servowrite head provided with a head face (21) having a longitudinal direction (L) along which a magnetic recording medium can be relatively moved with respect to the magnetic head, and a width direction (W) oriented transversely to the longitudinal direction. In order to write signals simultaneously in various tracks the write head is provided with a structure having integrated, juxtaposed write units (25a; 25b) extending substantially transversely to the longitudinal direction and the width direction and each being provided with at least one write gap (27a; 27b). One write gap of the one write unit and one write gap of the other write unit of every two adjacent write units are situated in mutually different planes (P1; P2) which are oriented substantially transversely to the longitudinal direction.
