Abstract
PURPOSE:To reduce the wear due to the contact between the core and the medium, by increasing the floating gap length between the core having the recording/reproducing gap and the flexible magnetic recording medium. CONSTITUTION:The magnetic head 4 consists of the core 13, groove 14, and slider 12, and the reproducing or recording gap is formed to the core 13. The surface of the core 13 and the slider 12 forms a part of the spherical surface entirely, and although the spherical radius is R, the core 13 part is recessed by the size delta than the spherical radius of the slider external circumference. Thus, since the amount of change in the medium for the core 13 is made smaller, the load pressure exerted from the medium to the core 13 is made smaller, and the medium is supported at the spherical surface of the slider external circumference, and the floating gap length of the core 13 is increased by the size delta than the slider external circumference, allowing to reduce wear.
