摘要： A kind of glass for magnetic head having a property of absorption of light and a property of adhesion in the molten state is produced as follows: CuO and Cr.sub.2 O.sub.3 are added to the glass of PbO-B.sub.2 O.sub.3 -SiO phase in order to increase the absorption rate from a laser beam. TeO.sub.2 is added in order to decrease the viscosity of the molten material and to increase the molten viscosity and the wettability to ceramics and ferrite which are bonded. It can be used in the fabrication of the magnetic head and the floating magnetic head. In particular the glass melts easily when irradiated by a xenon arc beam and other lasser beams.
