Abstract

An object of the invention is to manufacture sliders having excellent properties with accuracy and to improve the production efficiency and facilitate handling of intermediate products during slider manufacturing steps. In a method of the invention to manufacture a bar in which a row of slider sections are aligned, a wafer block is made from a wafer in which rows of slider sections are aligned. The wafer block is bonded to a dummy block on a support plate. Next, a processing step and a cutting step are repeated. The processing step is to perform specific processing on the medium facing surfaces of a row of slider sections in the medium facing surface of the wafer block bonded to the support plate. The cutting step is to cut the wafer block together with the support plate such that the row of slider sections whose medium facing surfaces have received the specific processing are separated from the wafer block to be the bar.

Claims7

Dependent claims

A method of manufacturing sliders by processing a slider aggregate that is made from a material including a plurality of rows of sections to be the sliders each having a medium facing surface, the slider aggregate including one of the rows of the sections to be the sliders whose medium facing surfaces receive a specific processing, the method including:

a first step of joining a support member to a surface of the material including surfaces of all the sections to be the sliders, the support member supporting all the sections to be the sliders in the material;
and
a second step of performing specific processing on the medium facing surfaces of a row of the sections to be the sliders located at one end of the material joined to the support member;
and cutting the material and the support member together such that the row of the sections to be the sliders whose medium facing surfaces have received the specific processing is separated from a remainder of the material, the second step being repeated until the slider aggregate is exhausted.
