Abstract

PURPOSE:To increase the floating stability of a magnetic head to the rotation of a magnetic disk, by controlling one or both widths of the two floating surfaces of a magnetic head. CONSTITUTION:The magnetic heads 1'' and 1''' are provided at a single side or both sides to a spindle center line 10 that gives the rotation to a magnetic disk 11. In such case, the travelling direction of the disk 11 coincides with the stable floating direction and the widths of floating surfaces 7 and 7' are controlled so as to not to induce unbalances (b) and (c) of the floating quantity owing to the variation of the pressure distributions of slider floating surfaces 7 and 7' of the magnetic head 1. For instance, the position of a groove 12 of the head 1 is shifted by A to the slider side having a larger floating degree to give a control to widths (a) and (a') of the floating surfaces. Thus the floating degree is well balanced.
