    • A magnetic head assembly of the present invention includes a head rail having a plurality of head element portions each including a MR element and sliding portions that come into contact with a magnetic tape, and a protective film on a magnetic tape sliding surface of the head element portions and the sliding portions, wherein the protective film is formed in a portion other than the vicinity of both ends of the head rail in a traveling direction, and an outermost surface of the protective film, on which a magnetic tape is capable of sliding, is formed flat. Thus, a magnetic head assembly used in a magnetic tape apparatus can be provided, in which an output does not decrease due to the abrasion deformation of the head element portions and the increase in spacing by the adhesion of stain.
    • 本发明的磁头组件包括具有多个磁头元件部分的磁头导轨,磁头元件部分各自包括MR元件和与磁带接触的滑动部分,以及在磁头元件的磁带滑动表面上的保护膜 部分和滑动部分,其中保护膜沿行进方向形成在头轨两端附近的部分中,以及保护膜的能够滑动的最外表面, 形成平坦。 因此,可以提供在磁带装置中使用的磁头组件,其中由于头元件部分的磨损变形而导致的输出不会减小,并且由于污渍的附着而增加间隔。
