Abstract: 1292945 Magnetic heads INTERNATIONAL BUSINESS MACHINES CORP 28 May 1971 [6 July 1970] 17816/71 Heading G5R Two portions of a magnetic core are bonded together by a crystallizable glass in its crystallized state, the glass defining a transducing gap. The core, which may be of a nickel-zinc ferrite, may be bonded to a barium titanate slider by a further glass which softens at a lower temperature than the crystallized gap glass. This further glass may be either crystallized or uncrystallized.
