A sanding tool includes a backing layer an adhesive layer and an abrasive layer. The adhesive layer is provided at the backing layer for bonding the abrasive layer at the backing layer via flocking techniques.

Flocking sanding tool and manufacturing method thereof

An elastic self-lubricating polishing tool includes an elastic grinding layer including an abrasive member and an elastic base layer affixed to the abrasive member, an absorbing layer absorbing and sustainedly releasing liquid inside of the absorbing layer, and an adhesive layer overlappedly connected with the elastic base layer of the elastic grinding layer and the absorbing layer. The elastic self-lubricating polishing tool is elastic and self-lubricating to sand and polish a surface of a workpiece.

Elastic self-lubricating polishing tool

The method of fabricating a magnetic head slider includes steps of: forming a first protective film on an air bearing surface of a magnetic head slider on which either a recording element or a reproduction element is formed or on which both a recording element and a reproduction element are formed; removing a portion of the first protective film to reduce the thickness of the first protective film and forming a second protective film over the first protective film that has been reduced in thickness; and forming an uneven portion for controlling the flying characteristics of the magnetic head slider on the air bearing surface of the magnetic head slider; wherein the formation of the uneven portion is carried out after the first protective film has been formed and before the second protective film is formed, or after the second protective film has been formed.

Method of fabricating magnetic head slider including partial removal step of protecting film

To provide a high-quality protection target by forming a protective film that is thin and excellent in corrosion resistance. Provided is a protective film forming method for forming a protective film at least on a surface of a protection target. The method comprises: a base film forming step for forming a base film on the surface of the protection target; and a DLC film forming step for forming a diamond-like carbon film on the base film. The base film forming step forms the base film on the surface of the protection target for a plurality of times by repeating a process of depositing the base film in a prescribed thickness and eliminating a part of or a whole part of the base film. Further, the method comprises, before the DLC film forming step, an insulating layer forming step for forming an insulating layer on the surface of the base film on which the diamond-like carbon film is to be formed.

Protective film forming method

A method for forming micro-texture on an air bearing surface of a magnetic read/write slider, includes: positioning sliders arranged in arrays on a tray, each slider having a pole tip facing upward; loading the tray into a processing chamber, which is then evacuated to a preset pressure; and introducing a processing gas containing oxygen into the processing chamber; exposing the sliders to etch the surface of the slider so as to form a clear two-step structure thereon.
