Abstract
A method for correcting an outer surface of a magnetic slider mainly made of ceramic to a desired surface shape, wherein a laser beam is applied to an outer face of a work piece (10) to partially melt a ceramic base, the melted part (20) is resolidfied, and the surface shape of the slider is exactly corrected to the desired shape by using shrinkage stress during the resolidification.
Claims8
A method for correcting an outer surface of a magnetic slider having a ceramic base to a desired surface shape,
- characterized in that pulse laser beams, each of which is converged as a spot beam, are applied to a plurality of parts of an outer face of a work piece to partially melt the ceramic base, the melted parts are resolidified, and the surface shape of the slider is corrected to the desired shape by using shrinkage stress during the resolidification.
A method for correcting an outer surface of a magnetic slider having a ceramic base to a desired surface shape,
- characterized in that a laser beam, which is converged as a linear beam, is applied to an outer face of a work piece to partially melt the ceramic base, the melted part is resolidified, and the surface shape of the slider is corrected to the desire shape by using shrinkage stress during the resolidification.
