Magnetic head devices for data cartridges.

摘要

A magnetic head device for a data cartridge includes a recording head having a recording magnetic gap and a reproducing head having a reproducing magnetic gap united in one body. The magnetic head device includes a first magnetic head element having a first magnetic gap, the first magnetic head element having center cores on both lateral sides thereof, second and third magnetic gaps formed by magnetic cores forming closed magnetic circuits in the center cores, the magnetic cores being bonded to each other via a gap member. The first to third magnetic gaps are arrayed in a magnetic recording medium rubbing direction. The magnetic cores forming the second and third magnetic gaps have inclined gap forming faces. The gap forming faces of the magnetic gaps extend in a depth direction in a manner non-parallel to one another. One of the first to third magnetic gaps is used as a recording magnetic gap. The recording magnetic gap has a magnetic metal film formed on the gap forming face thereof. The magnetic metal film is formed directly on the magnetic core without providing an underlying film. <IMAGE>
