ABSTRACT:
A floating magnetic head for use in a fixed-type magnetic disk drive has a slider with a coil groove defined therein and opening at the trailing end of the slider. The coil groove has a bottom remote whose width is smaller than the width of the coil groove at the trailing end. The coil groove may be tapered linearly or stepwise, and the bottom may be arcuate in shape. The slider has upper and lower walls between which the coil groove is defined, the upper and lower walls being progressively thicker toward the bottom of the coil groove. The progressively thicker upper and lower walls are mechanically strong against shocks and other excessive forces, and also against stresses applied from coils wound in multiple layers on a core tip inserted in a slit that is defined in the slider across the coil groove.
