Abstract: PURPOSE: To narrow the space between a head and a disk by making the surface area of two front air bearing pads of a slider larger than that of rear air bearing pad. CONSTITUTION: A midsection 28 of a slider of a converter assembly is a recessed surface and forms a non-air bearing surface. Sandwiching this midsection 28, two front air bearing pads 25 and 27 and a rear air bearing pad 29 are formed, and the area of the front air bearing surfaces is made larger than that of the rear air bearing surface. Therefore, as a slider is pitched up by the pads 25 and 27, the pad 29 also pitches up the slider, and air is made to flow under the pad 29 to form the air bearing. As a result, an air gap between a head and a disk with a lubricant film becomes narrow, and a slider of a converter assembly becomes resistant to influence by manufacturing parameter or variations in a disk diameter.

Abstract: PURPOSE: To minimize the operation of each element by forming a plurality of first channels in specified depth to a first flat surface on a wafer and slicing each line of a device from the wafer. CONSTITUTION: A plurality of vertical channels 41 are notched to the deposit surface of a wafer 36. It is favorable that the channel 41 has depth less than the half of the wafer 36. The channels are formed, and the wafer is removed from a holder, turned upside down, and mounted again. The channels are cut to the reverse surface, preferably depth less than the half of the wafer 36 of the wafer 36. Each channel is aligned with channels on the reverse side of the wafer 36. Since the total of each depth of an aligned channel pair is made smaller than the thickness of the whole wafer, the connecting sections of a substrate are left among device columns. The lines of sliders are sliced from the horizontal edge 33 of a wafer 31. Each line bar can be mounted on a working plane for succeeding line working.
