Abstract
1,152,721. Magnetic head. IIT RESEARCH INSTITUTE. 2 May, 1966, No. 19262/66. Heading G5R. In a magnetic head including a main or working core 10, an auxiliary core 20 is provided adjacent the main core for diverting residual flux produced by residual magnetism in the main core away from the head gap. A shunt return path is provided for the flux by the auxiliary core which is of low coercive force material. The auxiliary core may be separate from the working core 10 with the space therebetween 30 filled with a non-hardening material, e.g. silicon grease, or the auxiliary core 76, 77, Fig. 2C, may be integral with the working core 10c or the auxiliary core, Fig. 2A, may be formed of both separate 20a and integral 70a, 71a parts. The head may be supported in a pair of mounting blocks 241, 242, Fig. 6, of non- magnetic, electrically conducting material each of which is recessed to provide cavities 241b, 242b, which receive the toroidal head winding 275 and cavities 241a, 242a (not shown) in which the core halves are received and bonded. A keeper housing 260 is secured to the mounting blocks. Cross-field windings may be mounted on each pole tip, Figs. 8-10 (not shown), and one of the pole tips may be spaced from the tape path by a non-magnetic spacer, Fig. 11 (not shown).
