Abstract
PURPOSE:To hold a flexible magnetic recording medium over the medium-opposing surface at an average float height, by forming a magnetic head so that the sectional area of at least part of the trailing-side groove is less than that of the leading-side groove. CONSTITUTION:Head fitting window 6a of rotor 6 is fitted with magnetic head 1 with medium opposing surface 1b projected from rotor surface 6b. Medium-opposing surface 1b is spherical and near top T of the spherical surface, cores 9 and 9' forming gap 7 are provided. At both the side of the core, grooves 2 and 2' are made and at leading side 1c, they get wider and wider in groove width W in direction A while groove width W at trailing side 1a is narrower than that at leading side 1c and constant.
