摘要:
The present invention discloses a magnetic head which allows smooth filling of a non-magnetic material such as glass, and can prevent bubbles from generating within the such non-magnetic material, which comprises a slide-contact plane with which a magnetic recording medium comes into contact, which is provided on a magnetic core; a magnetic gap provided in the slide-contact plane by forming thereon at least a magnetic film; a groove portion provided at one end or each of both ends of the magnetic gap so as to be aligned approximately in parallel to a moving direction of the magnetic recording medium; and a non-magnetic material provided in the groove portion, wherein the groove portion has a non-magnetic oxide film and a chromium film formed on an inner surface thereof and has the non-magnetic material formed on the chromium film so as to fill the groove portion.
