摘要： Disclosed is a method of polishing a magnetic head slider whereby a by-processed step can be easily reduced. An air bearing surface of the magnetic head slider is polished with setting a bar that includes the magnetic head slider where a thin film magnetic head element is formed to reciprocate in a radius direction of a polishing plate, as well as rotating the polishing plate having a polishing surface. Polishing steps include a first polishing step of performing a height polish while rotating the polishing plate at a first velocity, and a second polishing step of performing a finishing polish while rotating the polishing plate at a second velocity sufficiently lower than the first velocity. The second velocity at the second polishing step is set so that an average linear velocity in the direction of the rotation of the polishing plate is equal to or lower than 0.032 m/s (preferably equal to or lower than 0.008 m/s). Consequently, the by-processed step that is generated on the air bearing surface of the magnetic head slider is reduced.

摘要： In a method for deoxygenating the secondary and/or tertiary OH group(s) in an alcohol having such OH group(s), a characteristic feature thereof is that the alcohol having the OH group(s) is first converted into a substituted or unsubstituted benzoate derivative, and the benzoate derivative is then subjected to a photocatalytic reaction in the presence of an electron donor or to an electrode reaction in the presence of an electrolyte, whereby the desired compound in which the OH group(s) has (have) been selectively deoxygenated can be obtained in a high yield on an industrial scale.
