ABSTRACT:
A magnetic head which is slidably in contact with a magneto-optical recording medium at the time of carrying out recording of information signals onto the magneto-optical recording medium. This magnetic head includes a magnetic core; a bobbin having an insertion hole into which the magnetic core is inserted, a recessed portion within which a coil is formed in a manner to surround the insertion hole, and a flange portion formed in a direction perpendicular to the length direction of the magnetic core and a slidable contact body having an attachment hole opened at one end for attaching the magnetic core and the bobbin. Either the peripheral edge of the attachment hole or a surface of a flange portion of the bobbin attached within the attachment hole constitutes a slidable surface of the magneto-optical recording medium. Further, an engagement portion is formed at either one of the bobbin and the slidable contact body, and a portion to be engaged is formed at the other member. The engagement portion and the portion to be engaged are engaged with each other, whereby the bobbin and the slidable contact body are integrated without use of a bonding agent. Thus, assembling of the magnetic head is carried out.
