ABSTRACT:
According to this invention a floating type magnetic head has a floating section in the form of rails on a magnetic slider and a magnetic gap is formed on the slider at an outermost side thereof so as to be capable of being positioned at an outermost circumference of a magnetic disk. Since the tracks located at the outermost circumference of a disk are the longest, the present invention allows the recording wavelength to be shortened and the recording density to be increased.
