Abstract

PURPOSE: To reduce fluctuation of a floating gap length between a magnetic head and a recording medium to reduce variance of the electromagnetic conversion characteristic, by providing a notched groove part in the air flowing-in side of the magnetic head.
CONSTITUTION: Magnetic head 2 is constituted with magnetic core part 4, groove part 5 which controls the floating gap length, and slider part 3 to obtain the floating gap. Notched groove part 10 is provided in air flowing-in side 8 across core part 4, groove part 5, and slider part 3. Since air pressure of groove part 10 becomes negative more than that of slider part 3, recording medium 1 is pulled toward groove part 10, and the gap part has the floating gap distribution linear in the longitudinal direction of core part 4 and becomes wide and minute. As a result, fluctuation of the floating gap length is reduced to stabilize the electromagnetic conversion characteristic.
