摘要： A magnetic head element has one or more rails formed on the surface thereof. Each rail is formed so as to have a tapered angle of 55.degree.-85.degree.. To form such a rail, ion milling is conducted; the rail substrate used is allowed to have an inclination angle to 15.degree.-60.degree. and is rotated; and there is used, as the ion milling gas, a fluorinated hydrocarbon (e.g. CH.sub.2 FCF.sub.3) gas alone or a mixed gas of said fluorinated hydrocarbon gas and Ar, SF.sub.6 or the like. Accordingly, a magnetic head rail shape gives a small variation in flying height between magnetic head and magnetic disc.

摘要： For removing re-deposited particulates produced during an etching process of a magnetic head slider and forming a minute chamfered portion, a polishing process is carried out by using polishing cloth such as non-woven polyester fabric after having formed rails of non-linear shape on a floating surface by the etching process. Thus, the re-deposited particulates produced during the etching process are removed, whereby the reliability of the floating characteristic of magnetic head is improved.

摘要： A rear projection apparatus having a projector containing a light source and a liquid crystal cell, a mirror for reflecting a light from the projector, and a screen for projecting the light reflected by the mirror. The screen is being composed of an optical film having an optical element capable of forming a spatial distribution of light transmittance, a light shield layer and a light diffusion layer. The light shield layer is positioned between the optical element and the light diffusion layer and is composed of a compound which changes light transmittance depending on irradiation of an energy beam. The light transmittance passing the light shield layer is modulated spatially depending on a dose of the energy beam.
