Magnetic head and magnetic head apparatus

摘要

A magnetic head (10) has a first magnetic head unit (12) for recording and reproducing information to and from a first flexible rotating recording medium; a second magnetic head unit (14) for recording and reproducing information to and from a second flexible rotating recording medium having a coercive force lower than a coercive force of the first flexible rotating recording medium; and a slider (16) supporting the first and second magnetic head units (12, 14), the slider (16) having a central groove (34) separating a first air bearing surface (18) at which the first magnetic head unit (12) is provided and a second air bearing surface (20) at which the second magnetic head unit (14) is provided, the slider (16) generating an elevating force from an air flow generated in a space between the first and second air bearing surfaces (18, 20) and the flexible rotating recording medium, the first air bearing surface (18) having a width on a leading edge side thereof perpendicular to a direction of approach of the flexible rotating recording medium and a width on a trailing edge side thereof disposed opposite the leading edge side, the width of the leading edge side being greater than the width of the trailing edge side.
