Abstract
A linear-type tape storage magnetic head device in which track density and the response of a magnetic head is improved is provided. A sliding portion constituting a main sliding surface in contact with a magnetic tape T and a magnetic head element chip portion. A tracking mechanism has a two-stage tracking mechanism of a rough-move tracking mechanism and a fine-move tracking mechanism, with the magnetic head element chip pardon being directly disposed in the fine-move tracking mechanism and the fine-move tracking mechanism being disposed in the rough-move tracking mechanism; the rough-move tracking mechanism makes the magnetic head element chip portion move across the tracks arranged in parallel in the width direction of the magnetic tape T; and the magnetic head element chip portion made lighter in weight provides improved speed-up and accuracy of tracking and high density of the tracks can be obtained.
