A CMP slurry comprising polishing abrasives containing mixture abrasives of silica and alumina is used. In CMP using the slurry comprising mixture abrasives of silica and alumina as polishing abrasives, a down force-dependency of a polishing rate is high and an increase in dishing can be effectively suppressed.

A manufacturing method of a thin-film magnetic head with a dishing suppressed in the case of planarizing a magnetic shield which a read head portion has or a magnetic pole which a write head portion has is provided. A manufacturing method of a thin-film magnetic head comprising a read head portion for data reading which has at least two magnetic layers functioning as a magnetic shield and a write head portion for data writing which has two magnetic layers functioning as a magnetic pole is provided, in a process forming at least the lowest magnetic layer in at least the two magnetic layers functioning as the magnetic shield and the two magnetic layers functioning as the magnetic pole in the case of forming a plurality of thin-film magnetic head patterns on an element formation surface of the wafer substrate, which comprises steps of: forming this magnetic layer so as to reach a position which becomes a medium opposed surface at a middle portion to a trick width direction in each thin-film magnetic head pattern, and forming a dishing prevention portion at a position farther than this magnetic layer from the position which becomes the medium opposed surface in both sides or either side along the track width direction of this magnetic layer; forming a nonmagnetic insulating layer so as to cover the magnetic layer and the dishing prevention portion; and planarizing and polishing the magnetic layer, the dishing prevention portion, and the nonmagnetic insulating layer thereafter.

A system for applying belt fasteners to belt ends is disclosed. The system includes a power tool apparatus and a guiding apparatus. The guide apparatus includes a guide block having guide bores in which attachment members, e.g., rivets, are held in position relative to the belt fasteners so that a drive rod of the power tool impacts the rivets in the guide block bores. The guide block preferably is of a hard material, e.g. a machined steel or powder steel, for proper guiding of the drive rod and rivet during riveting operations.
