    摘要： A magnetic core provided with one or more concave mark(s) with a depth of 2 um or less on at least one side surface of the magnetic core for a floating-type complex magnetic head, wherein the magnetic gap depth is controlled by machining the air bearing while observing a specific portion, from the direction perpendicular to the air bearing, of a concave mark or observing the level difference of specific portions of multiple concave marks provided on the side surface of the magnetic core in relation to the position of the apex of the magnetic core after cementing the magnetic core using glass filler inside a slit provided in the air bearing of a slider.
